Every great story has great characters. But what makes a great character? The main character is central to a story and needs to be “round” or complex, with depth and distinctive qualities. A cast of supporting characters can be of various types—even “flat” or uncomplicated ones, who nonetheless help move the story along.
A character is an individual (usually a person) in a narrative in a work of fiction or creative nonfiction . The act or method of creating a character in writing is known as characterization .
In British author E.M. Forster's 1927 “Aspects of the Novel,” Forster made a broad yet worthwhile distinction between flat and round characters. A flat (or two-dimensional) character embodies “a single idea or quality.” This character type, Forster wrote, “can be expressed in one sentence.”
In contrast, a round character responds to change: he or she “is capable of surprising [readers] in a convincing way,” Forster wrote. In certain forms of nonfiction , particularly biographies and autobiographies , a single character may serve as the primary focus of the text.
The word character comes from the Latin word meaning "mark, distinctive quality” and ultimately from the Greek word that means "scratch, engrave."

Observations on Character
In “Essentials of the Theory of Fiction,” Michael J. Hoffman and Patrick D. Murphy wrote:
- “If, in a sense, the flat character embodies an idea or quality, then the 'round' character encompasses many ideas and qualities, undergoing change and development, as well as entertaining different ideas and characteristics.” (Michael J. Hoffman and Patrick D. Murphy, Essentials of the Theory of Fiction , 2nd ed. Duke University Press, 1999)
Mr. Spock as a Round Character
- “Mr. Spock, my favorite character in ‘Star Trek,’ was James T. Kirk’s best friend and one of the most interesting characters ever written for television. Spock was a Vulcan-human hybrid who struggled for many years with his dual heritage before he finally found peace through acceptance of both parts of his heritage.” (Mary P. Taylor, Star Trek: Adventures in Time and Space, Pocket Books, 1999)
Thackeray’s Description of Lord Steyne
- “The candles lighted up Lord Steyne’s shining bald head, which was fringed with red hair. He had thick bushy eyebrows, with little twinkling bloodshot eyes, surrounded by a thousand wrinkles. His jaw was underhung, and when he laughed, two white buck-teeth protruded themselves and glistened savagely in the midst of the grin. He had been dining with royal personages, and wore his garter and ribbon. A short man was his lordship, broad-chested, and bow-legged, but proud of the fineness of his foot and ankle, and always caressing his garter-knee.” (William Makepeace Thackeray, Vanity Fair , 1847–48)
Narrator as a Character in the Personal Essay
- “[In a personal essay], the writer needs to build herself into a character. And I use the word character much the same way the fiction writer does. E.M. Forster, in ‘Aspects of a Novel,’ drew a famous distinction between ‘flat’ and ‘round’ characters—between those fictional personages seen from the outside who acted with the predictable consistency of caricatures, and those whose complexities or teeming inner lives we come to know. ... The art of characterization comes down to establishing a pattern of habits and actions for the person you are writing about and introducing variations into the system. ...
- The point is to begin to take inventory of yourself so that you can present that self to the reader as a specific, legible character. ...
- The need thus exists to make oneself into a character, whether the essay uses a first- or third-person narrative voice . I would further maintain that this process of turning oneself into a character is not self-absorbed navel-gazing. But rather a potential release from narcissism. It means you have achieved sufficient distance to begin to see yourself in the round: a necessary precondition to transcending the ego—or at least writing personal essays that can touch other people.” (Phillip Lopate, “Writing Personal Essays: On the Necessity of Turning Oneself Into a Character.” Writing Creative Nonfiction , edited by Carolyn Forché and Philip Gerard, Story Press, 2001)
Details of Character
- “ To achieve a fully dimensional character , fictional or real, a writer must watch people closely, much more closely than the average person would. He or she looks especially for anything unusual or distinct about the person or persons involved but does not ignore what is ordinary and typical. The writer then reports, in as interesting a way as possible, these poses, posturings, habitual gestures, mannerisms, appearances, glances. Not that the writer limits observations to these, but these frequently appear in creative nonfiction writing.” (Theodore A. Rees Cheney, Writing Creative Nonfiction: Fiction Techniques for Crafting Great Nonfiction, Ten Speed Press, 2001)
Composite Characters in Nonfiction
- “ The use of a composite character is a dubious device for the writer of nonfiction because it hovers in a gray region between reality and invention, but if it is employed the reader should be made aware of the fact early.” (William Ruehlmann, Stalking the Feature Story, Vintage Books, 1978)

Literature Review

- Request Info Request info for.... Undergraduate/Graduate Online Study Away Continuing & Professional Education International Student Services General Inquiries
The purpose of a literature review is to collect relevant, timely research on your chosen topic, and synthesize it into a cohesive summary of existing knowledge in the field. This then prepares you for making your own argument on that topic, or for conducting your own original research.
Depending on your field of study, literature reviews can take different forms. Some disciplines require that you synthesize your sources topically, organizing your paragraphs according to how your different sources discuss similar topics. Other disciplines require that you discuss each source in individual paragraphs, covering various aspects in that single article, chapter, or book.
Within your review of a given source, you can cover many different aspects, including (if a research study) the purpose, scope, methods, results, any discussion points, limitations, and implications for future research. Make sure you know which model your professor expects you to follow when writing your own literature reviews.
Tip : Literature reviews may or may not be a graded component of your class or major assignment, but even if it is not, it is a good idea to draft one so that you know the current conversations taking place on your chosen topic. It can better prepare you to write your own, unique argument.
Benefits of Literature Reviews
- Literature reviews allow you to gain familiarity with the current knowledge in your chosen field, as well as the boundaries and limitations of that field.
- Literature reviews also help you to gain an understanding of the theory(ies) driving the field, allowing you to place your research question into context.
- Literature reviews provide an opportunity for you to see and even evaluate successful and unsuccessful assessment and research methods in your field.
- Literature reviews prevent you from duplicating the same information as others writing in your field, allowing you to find your own, unique approach to your topic.
- Literature reviews give you familiarity with the knowledge in your field, giving you the chance to analyze the significance of your additional research.
Choosing Your Sources
When selecting your sources to compile your literature review, make sure you follow these guidelines to ensure you are working with the strongest, most appropriate sources possible.
Topically Relevant
Find sources within the scope of your topic
Appropriately Aged
Find sources that are not too old for your assignment
Find sources whose authors have authority on your topic
Appropriately “Published”
Find sources that meet your instructor’s guidelines (academic, professional, print, etc.)
Tip: Treat your professors and librarians as experts you can turn to for advice on how to locate sources. They are a valuable asset to you, so take advantage of them!
Organizing Your Literature Review
Synthesizing topically.
Some assignments require discussing your sources together, in paragraphs organized according to shared topics between them.
For example, in a literature review covering current conversations on Alison Bechdel’s Fun Home , authors may discuss various topics including:
- her graphic style
- her allusions to various literary texts
- her story’s implications regarding LGBT experiences in 20 th century America.
In this case, you would cluster your sources on these three topics. One paragraph would cover how the sources you collected dealt with Bechdel’s graphic style. Another, her allusions. A third, her implications.
Each of these paragraphs would discuss how the sources you found treated these topics in connection to one another. Basically, you compare and contrast how your sources discuss similar issues and points.
To determine these shared topics, examine aspects including:
- Definition of terms
- Common ground
- Issues that divide
- Rhetorical context
Summarizing Individually
Depending on the assignment, your professor may prefer that you discuss each source in your literature review individually (in their own, separate paragraphs or sections). Your professor may give you specific guidelines as far as what to cover in these paragraphs/sections.
If, for instance, your sources are all primary research studies, here are some aspects to consider covering:
- Participants
- Limitations
- Implications
- Significance
Each section of your literature review, in this case, will identify all of these elements for each individual article.
You may or may not need to separate your information into multiple paragraphs for each source. If you do, using proper headings in the appropriate citation style (APA, MLA, etc.) will help keep you organized.
If you are writing a literature review as part of a larger assignment, you generally do not need an introduction and/or conclusion, because it is embedded within the context of your larger paper.
If, however, your literature review is a standalone assignment, it is a good idea to include some sort of introduction and conclusion to provide your reader with context regarding your topic, purpose, and any relevant implications or further questions. Make sure you know what your professor is expecting for your literature review’s content.
Typically, a literature review concludes with a full bibliography of your included sources. Make sure you use the style guide required by your professor for this assignment.

Why is it important to do a literature review in research?

The importance of scientific communication in the healthcare industry

The Importance and Role of Biostatistics in Clinical Research
“A substantive, thorough, sophisticated literature review is a precondition for doing substantive, thorough, sophisticated research”. Boote and Baile 2005
Authors of manuscripts treat writing a literature review as a routine work or a mere formality. But a seasoned one knows the purpose and importance of a well-written literature review. Since it is one of the basic needs for researches at any level, they have to be done vigilantly. Only then the reader will know that the basics of research have not been neglected.

The aim of any literature review is to summarize and synthesize the arguments and ideas of existing knowledge in a particular field without adding any new contributions. Being built on existing knowledge they help the researcher to even turn the wheels of the topic of research. It is possible only with profound knowledge of what is wrong in the existing findings in detail to overpower them. For other researches, the literature review gives the direction to be headed for its success.
The common perception of literature review and reality:
As per the common belief, literature reviews are only a summary of the sources related to the research. And many authors of scientific manuscripts believe that they are only surveys of what are the researches are done on the chosen topic. But on the contrary, it uses published information from pertinent and relevant sources like
- Scholarly books
- Scientific papers
- Latest studies in the field
- Established school of thoughts
- Relevant articles from renowned scientific journals
and many more for a field of study or theory or a particular problem to do the following:
- Summarize into a brief account of all information
- Synthesize the information by restructuring and reorganizing
- Critical evaluation of a concept or a school of thought or ideas
- Familiarize the authors to the extent of knowledge in the particular field
- Encapsulate
- Compare & contrast
By doing the above on the relevant information, it provides the reader of the scientific manuscript with the following for a better understanding of it:
- It establishes the authors’ in-depth understanding and knowledge of their field subject
- It gives the background of the research
- Portrays the scientific manuscript plan of examining the research result
- Illuminates on how the knowledge has changed within the field
- Highlights what has already been done in a particular field
- Information of the generally accepted facts, emerging and current state of the topic of research
- Identifies the research gap that is still unexplored or under-researched fields
- Demonstrates how the research fits within a larger field of study
- Provides an overview of the sources explored during the research of a particular topic
Importance of literature review in research:
The importance of literature review in scientific manuscripts can be condensed into an analytical feature to enable the multifold reach of its significance. It adds value to the legitimacy of the research in many ways:
- Provides the interpretation of existing literature in light of updated developments in the field to help in establishing the consistency in knowledge and relevancy of existing materials
- It helps in calculating the impact of the latest information in the field by mapping their progress of knowledge.
- It brings out the dialects of contradictions between various thoughts within the field to establish facts
- The research gaps scrutinized initially are further explored to establish the latest facts of theories to add value to the field
- Indicates the current research place in the schema of a particular field
- Provides information for relevancy and coherency to check the research
- Apart from elucidating the continuance of knowledge, it also points out areas that require further investigation and thus aid as a starting point of any future research
- Justifies the research and sets up the research question
- Sets up a theoretical framework comprising the concepts and theories of the research upon which its success can be judged
- Helps to adopt a more appropriate methodology for the research by examining the strengths and weaknesses of existing research in the same field
- Increases the significance of the results by comparing it with the existing literature
- Provides a point of reference by writing the findings in the scientific manuscript
- Helps to get the due credit from the audience for having done the fact-finding and fact-checking mission in the scientific manuscripts
- The more the reference of relevant sources of it could increase more of its trustworthiness with the readers
- Helps to prevent plagiarism by tailoring and uniquely tweaking the scientific manuscript not to repeat other’s original idea
- By preventing plagiarism , it saves the scientific manuscript from rejection and thus also saves a lot of time and money
- Helps to evaluate, condense and synthesize gist in the author’s own words to sharpen the research focus
- Helps to compare and contrast to show the originality and uniqueness of the research than that of the existing other researches
- Rationalizes the need for conducting the particular research in a specified field
- Helps to collect data accurately for allowing any new methodology of research than the existing ones
- Enables the readers of the manuscript to answer the following questions of its readers for its better chances for publication
- What do the researchers know?
- What do they not know?
- Is the scientific manuscript reliable and trustworthy?
- What are the knowledge gaps of the researcher?
22. It helps the readers to identify the following for further reading of the scientific manuscript:
- What has been already established, discredited and accepted in the particular field of research
- Areas of controversy and conflicts among different schools of thought
- Unsolved problems and issues in the connected field of research
- The emerging trends and approaches
- How the research extends, builds upon and leaves behind from the previous research
A profound literature review with many relevant sources of reference will enhance the chances of the scientific manuscript publication in renowned and reputed scientific journals .

Conducting a Literature Review
Benefits of conducting a literature review.

- Additional Resources
- Literature Review Tutorial by American University Library
- The Literature Review: A Few Tips On Conducting It by University of Toronto
- Write a Literature Review by UC Santa Cruz University Library
While there might be many reasons for conducting a literature review, following are four key outcomes of doing the review.
Assessment of the current state of research on a topic . This is probably the most obvious value of the literature review. Once a researcher has determined an area to work with for a research project, a search of relevant information sources will help determine what is already known about the topic and how extensively the topic has already been researched.
Identification of the experts on a particular topic . One of the additional benefits derived from doing the literature review is that it will quickly reveal which researchers have written the most on a particular topic and are, therefore, probably the experts on the topic. Someone who has written twenty articles on a topic or on related topics is more than likely more knowledgeable than someone who has written a single article. This same writer will likely turn up as a reference in most of the other articles written on the same topic. From the number of articles written by the author and the number of times the writer has been cited by other authors, a researcher will be able to assume that the particular author is an expert in the area and, thus, a key resource for consultation in the current research to be undertaken.
Identification of key questions about a topic that need further research . In many cases a researcher may discover new angles that need further exploration by reviewing what has already been written on a topic. For example, research may suggest that listening to music while studying might lead to better retention of ideas, but the research might not have assessed whether a particular style of music is more beneficial than another. A researcher who is interested in pursuing this topic would then do well to follow up existing studies with a new study, based on previous research, that tries to identify which styles of music are most beneficial to retention.
Determination of methodologies used in past studies of the same or similar topics. It is often useful to review the types of studies that previous researchers have launched as a means of determining what approaches might be of most benefit in further developing a topic. By the same token, a review of previously conducted studies might lend itself to researchers determining a new angle for approaching research.
Upon completion of the literature review, a researcher should have a solid foundation of knowledge in the area and a good feel for the direction any new research should take. Should any additional questions arise during the course of the research, the researcher will know which experts to consult in order to quickly clear up those questions.

Frequently asked questions
What is the purpose of a literature review.
There are several reasons to conduct a literature review at the beginning of a research project:
- To familiarize yourself with the current state of knowledge on your topic
- To ensure that you’re not just repeating what others have already done
- To identify gaps in knowledge and unresolved problems that your research can address
- To develop your theoretical framework and methodology
- To provide an overview of the key findings and debates on the topic
Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.
Frequently asked questions: Academic writing
You may have seen both “appendices” or “appendixes” as pluralizations of “ appendix .” Either spelling can be used, but “appendices” is more common (including in APA Style ). Consistency is key here: make sure you use the same spelling throughout your paper.
The purpose of a lab report is to demonstrate your understanding of the scientific method with a hands-on lab experiment. Course instructors will often provide you with an experimental design and procedure. Your task is to write up how you actually performed the experiment and evaluate the outcome.
In contrast, a research paper requires you to independently develop an original argument. It involves more in-depth research and interpretation of sources and data.
A lab report is usually shorter than a research paper.
The sections of a lab report can vary between scientific fields and course requirements, but it usually contains the following:
- Title: expresses the topic of your study
- Abstract: summarizes your research aims, methods, results, and conclusions
- Introduction: establishes the context needed to understand the topic
- Method: describes the materials and procedures used in the experiment
- Results: reports all descriptive and inferential statistical analyses
- Discussion: interprets and evaluates results and identifies limitations
- Conclusion: sums up the main findings of your experiment
- References: list of all sources cited using a specific style (e.g. APA)
- Appendices: contains lengthy materials, procedures, tables or figures
A lab report conveys the aim, methods, results, and conclusions of a scientific experiment . Lab reports are commonly assigned in science, technology, engineering, and mathematics (STEM) fields.
The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .
If you’ve gone over the word limit set for your assignment, shorten your sentences and cut repetition and redundancy during the editing process. If you use a lot of long quotes , consider shortening them to just the essentials.
If you need to remove a lot of words, you may have to cut certain passages. Remember that everything in the text should be there to support your argument; look for any information that’s not essential to your point and remove it.
Revising, proofreading, and editing are different stages of the writing process .
- Revising is making structural and logical changes to your text—reformulating arguments and reordering information.
- Editing refers to making more local changes to things like sentence structure and phrasing to make sure your meaning is conveyed clearly and concisely.
- Proofreading involves looking at the text closely, line by line, to spot any typos and issues with consistency and correct them.
The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .
A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .
It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.
Avoid citing sources in your abstract . There are two reasons for this:
- The abstract should focus on your original research, not on the work of others.
- The abstract should be self-contained and fully understandable without reference to other sources.
There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.
An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:
- To help potential readers determine the relevance of your paper for their own research.
- To communicate your key findings to those who don’t have time to read the whole paper.
Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.
In a scientific paper, the methodology always comes after the introduction and before the results , discussion and conclusion . The same basic structure also applies to a thesis, dissertation , or research proposal .
Depending on the length and type of document, you might also include a literature review or theoretical framework before the methodology.
Whether you’re publishing a blog, submitting a research paper , or even just writing an important email, there are a few techniques you can use to make sure it’s error-free:
- Take a break : Set your work aside for at least a few hours so that you can look at it with fresh eyes.
- Proofread a printout : Staring at a screen for too long can cause fatigue – sit down with a pen and paper to check the final version.
- Use digital shortcuts : Take note of any recurring mistakes (for example, misspelling a particular word, switching between US and UK English , or inconsistently capitalizing a term), and use Find and Replace to fix it throughout the document.
If you want to be confident that an important text is error-free, it might be worth choosing a professional proofreading service instead.
Editing and proofreading are different steps in the process of revising a text.
Editing comes first, and can involve major changes to content, structure and language. The first stages of editing are often done by authors themselves, while a professional editor makes the final improvements to grammar and style (for example, by improving sentence structure and word choice ).
Proofreading is the final stage of checking a text before it is published or shared. It focuses on correcting minor errors and inconsistencies (for example, in punctuation and capitalization ). Proofreaders often also check for formatting issues, especially in print publishing.
The cost of proofreading depends on the type and length of text, the turnaround time, and the level of services required. Most proofreading companies charge per word or page, while freelancers sometimes charge an hourly rate.
For proofreading alone, which involves only basic corrections of typos and formatting mistakes, you might pay as little as $0.01 per word, but in many cases, your text will also require some level of editing , which costs slightly more.
It’s often possible to purchase combined proofreading and editing services and calculate the price in advance based on your requirements.
There are many different routes to becoming a professional proofreader or editor. The necessary qualifications depend on the field – to be an academic or scientific proofreader, for example, you will need at least a university degree in a relevant subject.
For most proofreading jobs, experience and demonstrated skills are more important than specific qualifications. Often your skills will be tested as part of the application process.
To learn practical proofreading skills, you can choose to take a course with a professional organization such as the Society for Editors and Proofreaders . Alternatively, you can apply to companies that offer specialized on-the-job training programmes, such as the Scribbr Academy .

Conduct a literature review
What is a literature review.
A literature review is a summary of the published work in a field of study. This can be a section of a larger paper or article, or can be the focus of an entire paper. Literature reviews show that you have examined the breadth of knowledge and can justify your thesis or research questions. They are also valuable tools for other researchers who need to find a summary of that field of knowledge.
Unlike an annotated bibliography, which is a list of sources with short descriptions, a literature review synthesizes sources into a summary that has a thesis or statement of purpose—stated or implied—at its core.
How do I write a literature review?
Step 1: define your research scope.
- What is the specific research question that your literature review helps to define?
- Are there a maximum or minimum number of sources that your review should include?
Ask us if you have questions about refining your topic, search methods, writing tips, or citation management.
Step 2: Identify the literature
Start by searching broadly. Literature for your review will typically be acquired through scholarly books, journal articles, and/or dissertations. Develop an understanding of what is out there, what terms are accurate and helpful, etc., and keep track of all of it with citation management tools . If you need help figuring out key terms and where to search, ask us .
Use citation searching to track how scholars interact with, and build upon, previous research:
- Mine the references cited section of each relevant source for additional key sources
- Use Google Scholar or Scopus to find other sources that have cited a particular work
Step 3: Critically analyze the literature
Key to your literature review is a critical analysis of the literature collected around your topic. The analysis will explore relationships, major themes, and any critical gaps in the research expressed in the work. Read and summarize each source with an eye toward analyzing authority, currency, coverage, methodology, and relationship to other works. The University of Toronto's Writing Center provides a comprehensive list of questions you can use to analyze your sources.
Step 4: Categorize your resources
Divide the available resources that pertain to your research into categories reflecting their roles in addressing your research question. Possible ways to categorize resources include organization by:
- methodology
- theoretical/philosophical approach
Regardless of the division, each category should be accompanied by thorough discussions and explanations of strengths and weaknesses, value to the overall survey, and comparisons with similar sources. You may have enough resources when:
- You've used multiple databases and other resources (web portals, repositories, etc.) to get a variety of perspectives on the research topic.
- The same citations are showing up in a variety of databases.

A combination of these categories is also common cases. For instance, a literature review is a kind of research outcomes focus and its goal is also for integration to make generalization of a topic.To acquire more information about Cooper's Taxonomy of Literature Review, you can read more in [1] and [2].
One of the most difficult things in writing a literature review of novice researchers is that they do not know where to start and how to do it in an efficient way. To give some hints for the inexperienced researchers, this part describes briefly the process of conducting a literature review. Basically, there are 6 main steps (mainly extracted from [1]) in working on the literature. The process spreads from specifying type of the review to presenting the review.
i. Specifying type of the review A literature review can be one or a combination of several types described in previous part (Cooper's Taxonomy of Literature review). Positioning your type of the review will help you to orientate your process of conducting the review, especially in the next step - choosing review questions.
ii. Choosing review questions There is a distinction between review questions and empirical questions in a research [1]. The review questions refer to those questions which will be answered during the literature review while the empirical questions will be experimented and answered during the primary research conducted by researcher. At this stage, the review questions are concerned and formed. To form the review questions, two sub-steps are needed: Forming the questions and indicating filtering criteria [1].
- Forming questions: Review questions are very essential and influence the whole process of the review. These questions are not only lightening your search but also directing you in evaluating, analyzing and interpreting collected data; It can be thought as compass for exploring "the forest" of knowledge and finding out your own path of the review. As mentioned, the review types influence this forming step largely. For example, "From the previous literature, what is the effect of intervention X on outcomes Y and Z" [1] is a question focusing on the goal of integrating research outcomes. In particular, a similar question can be "How can peer-communication influence to learning java programming in online manner?".
- Filtering criteria for qualified data: While the review questions are useful to help the novice researchers to locate resources, filtering criteria are necessary and crucial in narrowing down or focusing on relevant resources. These kind of criteria are called criteria for inclusion and exclusion [1]. Indeed, these criteria should be considered as conditions for classifying collected resources (e.g. articles, papers...) into two folds: relevance (inclusion) and irrelevance (exclusion). The criteria are good enough if there is a similar classification result after giving the same set of resources to two persons classifying based on these criteria [1].
iii. Locating resources / data The main aim of this stage is to collect relevant resources lightened by the review questions based on the established filtering criteria. Normally, this stage will consume large time of the whole process. Nowadays, locating resources is almost done based on internet search. The search can be varied from common and popular sources such as search engines (e.g. Google), pages (wiki, blogs, research group website...) to specific and more professional places like e-libraries (ACM, Springer Link, ...), specific online journals (e.g. Ed/ITLib, Journal of Interactive Online Learning...). There are some practical recommendations which the novice researchers need to be paid attention while doing the searches. More often than not, qualified and valuable data is found at professional places rather than from results given by common search engines. But the common search engines can give good clues for further searches.
- Initializing the search from your existing knowledge, try to use keywords or combination of the keywords
- Logging your searches as much informative as possible such as: where you found the articles, which articles relate to which concepts, what are your thinking and decisions from each paper, who are authors of the papers, which authors or research groups have had much influence in the specific areas, etc.
- Expanding the searches by following references of valuable articles which have been found [1]
- Asking and consulting colleagues and experts (e.g. your supervisors) about your search results periodically [1]
- The search can be stopped when the researchers think that the collected data is rich enough to convince readers and that the questions are answered reasonably by the collected data [1].
iv. Evaluating data This step is very important for convincing readers (e.g. reviewers, supervisors). In this step, the researcher has to inspect very careful and deeply the collected data retrieved in previous step. Here again the review types play a very important role in evaluation, it means the evaluated data must support the selected types of the review. For example, if the review is characterized by the focus and its goals are research outcomes and integration, the evaluated data retrieved from the articles must express the achieved results of previous researches and an integration of these results must be considered and obtained [1]. Moreover, the following aspects should also be investigated: what kind of the type of evaluated data is? How was the process or instrument used to gather data? What methodologies were used to analyze the collected data? etc. This information has to be recorded carefully in appropriate form, for example, coding book is recommended in [1].
v. Analyzing and synthesizing This step is continuity of the evaluating step. In this stage, the author has to put her own ideas on the evaluated data. A holistic picture of the research area should be exposed such as what have been done by previous researches; what are the gaps and where are the problems which will be solved in the primary research. The synthesis of the review can be done in various ways decided by the collected data, these ways can be quantitative, qualitative or mixed approaches [1].
vi. Publishing the work Finally, the whole work will be arranged and organized based on your purpose such as historically, conceptually and methodologically [1] then a presentation of the review can be published or sent to target readers.
The paper "Survey on Context-Aware Pervasive Learning Environments" [5] is a very good example of a literature review, I think. It has had a very clear structure and good approach to reach the aim - presenting the current state-of-the-art of Context-aware pervasive learning environment. In the introduction part of the paper, authors have specified very clear about type of the review, the goal of the review is integration and identification of central issues based on observing and evaluating research outcomes of existing applications and practices: " By reviewing existing work, we seek to build a solid ground for further research on how different learning models can be efficiently utilised in pervasive learning environments and what are the critical features of such an environment " [5]. The method used in the paper to conduct the survey is also similar with the strategies discussed above: formulating research questions, Collecting data, evaluating data and observing (analyzing and synthesizing). The followings are some particular examples extracted from the paper.
- Research questions: These questions are very important for later steps. The questions are not primary research questions but they are for review research. The followings are 3 main questions created by the author of the paper [5].
- Data collection: Before gathering the data the authors has created a set of rules for inclusion, some example rules from the paper are: a) The work describes a design, implementation, analysis or test of a pervasive learning environment or system; b) The presented environment/system uses sensors or other technologies for smart environments to enable context-awareness; having people walking around with mobile devices connected to a wireless network was not enough as it is merely m-learning; etc. [5]
There were 18 qualified papers chosen for the survey from many papers or articles passing two phases. In the first phase, titles and abstracts of papers or articles in given forums were investigated. If there were relevance the papers were chosen to the next phase. In the second phase, the abstracts and introductions were read carefully. Just only those met the inclusion criteria were selected for the survey.
- Data evaluation: to extract useful information from the selected papers, the authors has created a set of detail questions derived from the research questions. These detail questions have lightened the author to retrieve relevant information which supporting deeper analysis. Some example questions from the paper are: Q-A0: What are the description and purpose of the system/environment? Q-A1: Is it based on a client/server approach? If not, what is it based on? Q-A2: What is the hardware/software platform of the system? etc. [5]
- Observation 1 : RFID (Radio Frequency IDentification) is the most prevalent sensor technology used in pervasive learning environments.
- Observation 2 : There are several learning models that are suitable for different learning activities in pervasive learning environments, but none of them was validated properly
- Other observations: see in the paper [5]
The important thing is that these observations were made on the basic of the detail questions created in the data evaluation stage.
- Presentation: The result of the review has been presented in the format of empirical paper including introduction, method, results, and discussion parts [1].
A good example of literature review was done by Alex Wilson and Janet Sarson about "Participation of Aboriginal Students in Postsecondary Health Education Programs in Saskatchewan." [6]
The author started with the project/research goals and followed a brief hstory of the topic. And then the authors specified the problem statements that they planned to expend deeply and discuss more step by step.
After the Introduction section, the authors discussed the first problem related to the research topic. They presented their points in the first sentence directly, then followed the found from the article or paper, which was cited from (Aboriginal Population Profile, 2006 Census, 2008; Saskatchewan Bureau of Statistics, n.d.), and ended with another issue that would be ready for the discussion in the next paragraph. In the second section, the authors use the same style to directly state the problem and follow the facts found in articles, journal papers, and statistics reports from the grovernment.
So, the entire literature review is structured in this style:
- Directly give out the research or project goals,
- Clearly state the problems,
- Briefly introduce the history related to the topic,
- Deeply expend each problem statement with facts found in jpurnal papers and reports,
- Intently identify areas of controversy in the literature,
- The review synthesize results into a summary of what is and is not known,
- The review materials are organized around based on the themes and trends.
For instance, the project goal is “to improve coordination of health programming, reduce administrative duplication, better adapt programs to the needs of First Nations and address the gaps in health services for First Nations people” which was cited from (Government of Saskatchewan, 2008), and then in the next paragraph, the authors use these statistic data to support the prolem statement mentioned previously.
In addition, the authors referred wide enough and good quality resources for this review. For instance, statistic reports from Statistics Canada , research paper from Canadian Council on Learning , and journal paper from Canadian Journal of Native Education , etc.

Research on research? If you find this idea rather peculiar, know that nowadays, with the huge amount of information produced daily all around the world, it is becoming more and more difficult to keep up to date with all of it. In addition to the sheer amount of research, there is also its origin. We are witnessing the economic and intellectual emergence of countries like China, Brazil, Turkey, and United Arab Emirates, for example, that are producing scholarly literature in their own languages. So, apart from the effort of gathering information, there must also be translators prepared to unify all of it in a single language to be the object of the literature survey. At Elsevier, our team of translators is ready to support researchers by delivering high-quality scientific translations , in several languages, to serve their research – no matter the topic.
What is a literature review?
A literature review is a study – or, more accurately, a survey – involving scholarly material, with the aim to discuss published information about a specific topic or research question. Therefore, to write a literature review, it is compulsory that you are a real expert in the object of study. The results and findings will be published and made available to the public, namely scientists working in the same area of research.
How to Write a Literature Review
First of all, don’t forget that writing a literature review is a great responsibility. It’s a document that is expected to be highly reliable, especially concerning its sources and findings. You have to feel intellectually comfortable in the area of study and highly proficient in the target language; misconceptions and errors do not have a place in a document as important as a literature review. In fact, you might want to consider text editing services, like those offered at Elsevier, to make sure your literature is following the highest standards of text quality. You want to make sure your literature review is memorable by its novelty and quality rather than language errors.
Writing a literature review requires expertise but also organization. We cannot teach you about your topic of research, but we can provide a few steps to guide you through conducting a literature review:
- Choose your topic or research question: It should not be too comprehensive or too limited. You have to complete your task within a feasible time frame.
- Set the scope: Define boundaries concerning the number of sources, time frame to be covered, geographical area, etc.
- Decide which databases you will use for your searches: In order to search the best viable sources for your literature review, use highly regarded, comprehensive databases to get a big picture of the literature related to your topic.
- Search, search, and search: Now you’ll start to investigate the research on your topic. It’s critical that you keep track of all the sources. Start by looking at research abstracts in detail to see if their respective studies relate to or are useful for your own work. Next, search for bibliographies and references that can help you broaden your list of resources. Choose the most relevant literature and remember to keep notes of their bibliographic references to be used later on.
- Review all the literature, appraising carefully it’s content: After reading the study’s abstract, pay attention to the rest of the content of the articles you deem the “most relevant.” Identify methodologies, the most important questions they address, if they are well-designed and executed, and if they are cited enough, etc.
If it’s the first time you’ve published a literature review, note that it is important to follow a special structure. Just like in a thesis, for example, it is expected that you have an introduction – giving the general idea of the central topic and organizational pattern – a body – which contains the actual discussion of the sources – and finally the conclusion or recommendations – where you bring forward whatever you have drawn from the reviewed literature. The conclusion may even suggest there are no agreeable findings and that the discussion should be continued.
Why are literature reviews important?
Literature reviews constantly feed new research, that constantly feeds literature reviews…and we could go on and on. The fact is, one acts like a force over the other and this is what makes science, as a global discipline, constantly develop and evolve. As a scientist, writing a literature review can be very beneficial to your career, and set you apart from the expert elite in your field of interest. But it also can be an overwhelming task, so don’t hesitate in contacting Elsevier for text editing services, either for profound edition or just a last revision. We guarantee the very highest standards. You can also save time by letting us suggest and make the necessary amendments to your manuscript, so that it fits the structural pattern of a literature review. Who knows how many worldwide researchers you will impact with your next perfectly written literature review.

A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated. Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic and to demonstrate to your readers how your research fits within a larger field of study.

Importance of a Good Literature Review
A literature review may consist of simply a summary of key sources, but in the social sciences, a literature review usually has an organizational pattern and combines both summary and synthesis, often within specific conceptual categories . A summary is a recap of the important information of the source, but a synthesis is a re-organization, or a reshuffling, of that information in a way that informs how you are planning to investigate a research problem. The analytical features of a literature review might:
- Give a new interpretation of old material or combine new with old interpretations,
- Trace the intellectual progression of the field, including major debates,
- Depending on the situation, evaluate the sources and advise the reader on the most pertinent or relevant research, or
- Usually in the conclusion of a literature review, identify where gaps exist in how a problem has been researched to date.
Given this, the purpose of a literature review is to:
- Place each work in the context of its contribution to understanding the research problem being studied.
- Describe the relationship of each work to the others under consideration.
- Identify new ways to interpret prior research.
- Reveal any gaps that exist in the literature.
- Resolve conflicts amongst seemingly contradictory previous studies.
- Identify areas of prior scholarship to prevent duplication of effort.
- Point the way in fulfilling a need for additional research.
- Locate your own research within the context of existing literature [very important].

Types of Literature Reviews
It is important to think of knowledge in a given field as consisting of three layers. First, there are the primary studies that researchers conduct and publish. Second are the reviews of those studies that summarize and offer new interpretations built from and often extending beyond the primary studies. Third, there are the perceptions, conclusions, opinion, and interpretations that are shared informally among scholars that become part of the body of epistemological traditions within the field.
In composing a literature review, it is important to note that it is often this third layer of knowledge that is cited as "true" even though it often has only a loose relationship to the primary studies and secondary literature reviews. Given this, while literature reviews are designed to provide an overview and synthesis of pertinent sources you have explored, there are a number of approaches you could adopt depending upon the type of analysis underpinning your study.
Argumentative Review This form examines literature selectively in order to support or refute an argument, deeply embedded assumption, or philosophical problem already established in the literature. The purpose is to develop a body of literature that establishes a contrarian viewpoint. Given the value-laden nature of some social science research [e.g., educational reform; immigration control], argumentative approaches to analyzing the literature can be a legitimate and important form of discourse. However, note that they can also introduce problems of bias when they are used to make summary claims of the sort found in systematic reviews [see below].
Integrative Review Considered a form of research that reviews, critiques, and synthesizes representative literature on a topic in an integrated way such that new frameworks and perspectives on the topic are generated. The body of literature includes all studies that address related or identical hypotheses or research problems. A well-done integrative review meets the same standards as primary research in regard to clarity, rigor, and replication. This is the most common form of review in the social sciences.
Historical Review Few things rest in isolation from historical precedent. Historical literature reviews focus on examining research throughout a period of time, often starting with the first time an issue, concept, theory, phenomena emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and to identify the likely directions for future research.
Methodological Review A review does not always focus on what someone said [findings], but how they came about saying what they say [method of analysis]. Reviewing methods of analysis provides a framework of understanding at different levels [i.e. those of theory, substantive fields, research approaches, and data collection and analysis techniques], how researchers draw upon a wide variety of knowledge ranging from the conceptual level to practical documents for use in fieldwork in the areas of ontological and epistemological consideration, quantitative and qualitative integration, sampling, interviewing, data collection, and data analysis. This approach helps highlight ethical issues which you should be aware of and consider as you go through your own study.
Systematic Review This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research, and to collect, report, and analyze data from the studies that are included in the review. The goal is to deliberately document, critically evaluate, and summarize scientifically all of the research about a clearly defined research problem . Typically it focuses on a very specific empirical question, often posed in a cause-and-effect form, such as "To what extent does A contribute to B?" This type of literature review is primarily applied to examining prior research studies in clinical medicine and allied health fields, but it is increasingly being used in the social sciences.
Theoretical Review The purpose of this form is to examine the corpus of theory that has accumulated in regard to an issue, concept, theory, phenomena. The theoretical literature review helps to establish what theories already exist, the relationships between them, to what degree the existing theories have been investigated, and to develop new hypotheses to be tested. Often this form is used to help establish a lack of appropriate theories or reveal that current theories are inadequate for explaining new or emerging research problems. The unit of analysis can focus on a theoretical concept or a whole theory or framework.
NOTE : Most often the literature review will incorporate some combination of types. For example, a review that examines literature supporting or refuting an argument, assumption, or philosophical problem related to the research problem will also need to include writing supported by sources that establish the history of these arguments in the literature.

Structure and Writing Style
I. Thinking About Your Literature Review
The structure of a literature review should include the following in support of understanding the research problem :
- An overview of the subject, issue, or theory under consideration, along with the objectives of the literature review,
- Division of works under review into themes or categories [e.g. works that support a particular position, those against, and those offering alternative approaches entirely],
- An explanation of how each work is similar to and how it varies from the others,
- Conclusions as to which pieces are best considered in their argument, are most convincing of their opinions, and make the greatest contribution to the understanding and development of their area of research.
The critical evaluation of each work should consider :
- Provenance -- what are the author's credentials? Are the author's arguments supported by evidence [e.g. primary historical material, case studies, narratives, statistics, recent scientific findings]?
- Methodology -- were the techniques used to identify, gather, and analyze the data appropriate to addressing the research problem? Was the sample size appropriate? Were the results effectively interpreted and reported?
- Objectivity -- is the author's perspective even-handed or prejudicial? Is contrary data considered or is certain pertinent information ignored to prove the author's point?
- Persuasiveness -- which of the author's theses are most convincing or least convincing?
- Validity -- are the author's arguments and conclusions convincing? Does the work ultimately contribute in any significant way to an understanding of the subject?
II. Development of the Literature Review
Four Basic Stages of Writing 1. Problem formulation -- which topic or field is being examined and what are its component issues? 2. Literature search -- finding materials relevant to the subject being explored. 3. Data evaluation -- determining which literature makes a significant contribution to the understanding of the topic. 4. Analysis and interpretation -- discussing the findings and conclusions of pertinent literature.
Consider the following issues before writing the literature review: Clarify If your assignment is not specific about what form your literature review should take, seek clarification from your professor by asking these questions: 1. Roughly how many sources would be appropriate to include? 2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)? 3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue? 4. Should I evaluate the sources in any way beyond evaluating how they relate to understanding the research problem? 5. Should I provide subheadings and other background information, such as definitions and/or a history? Find Models Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you've already read, such as required readings in the course syllabus, are also excellent entry points into your own research. Narrow the Topic The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that's available about the topic, but you'll make the act of reviewing easier if you first limit scope of the research problem. A good strategy is to begin by searching the USC Libraries Catalog for recent books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text. Consider Whether Your Sources are Current Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a "hot topic" and what is not.
III. Ways to Organize Your Literature Review
Chronology of Events If your review follows the chronological method, you could write about the materials according to when they were published. This approach should only be followed if a clear path of research building on previous research can be identified and that these trends follow a clear chronological order of development. For example, a literature review that focuses on continuing research about the emergence of German economic power after the fall of the Soviet Union. By Publication Order your sources by publication chronology, then, only if the order demonstrates a more important trend. For instance, you could order a review of literature on environmental studies of brown fields if the progression revealed, for example, a change in the soil collection practices of the researchers who wrote and/or conducted the studies. Thematic [“conceptual categories”] Thematic reviews of literature are organized around a topic or issue, rather than the progression of time. However, progression of time may still be an important factor in a thematic review. For example, a review of the Internet’s impact on American presidential politics could focus on the development of online political satire. While the study focuses on one topic, the Internet’s impact on American presidential politics, it will still be organized chronologically reflecting technological developments in media. The only difference here between a "chronological" and a "thematic" approach is what is emphasized the most: the role of the Internet in presidential politics. Note however that more authentic thematic reviews tend to break away from chronological order. A review organized in this manner would shift between time periods within each section according to the point made. Note that this is the most common approach in the social and behavioral sciences. Methodological A methodological approach focuses on the methods utilized by the researcher. For the Internet in American presidential politics project, one methodological approach would be to look at cultural differences between the portrayal of American presidents on American, British, and French websites. Or the review might focus on the fundraising impact of the Internet on a particular political party. A methodological scope will influence either the types of documents in the review or the way in which these documents are discussed.
Other Sections of Your Literature Review Once you've decided on the organizational method for your literature review, the sections you need to include in the paper should be easy to figure out because they arise from your organizational strategy. In other words, a chronological review would have subsections for each vital time period; a thematic review would have subtopics based upon factors that relate to the theme or issue. However, sometimes you may need to add additional sections that are necessary for your study, but do not fit in the organizational strategy of the body. What other sections you include in the body is up to you. However, only include what is necessary for the reader to locate your study within the larger scholarship about the research problem.
Here are examples of other sections, usually in the form of a single paragraph, you may need to include depending on the type of review you write:
- Current Situation : Information necessary to understand the current topic or focus of the literature review.
- Sources Used : Describes the methods and resources [e.g., databases] you used to identify the literature you reviewed.
- History : The chronological progression of the field, the literature, or an idea that is necessary to understand the literature review, if the body of the literature review is not already a chronology.
- Selection Methods : Criteria you used to select (and perhaps exclude) sources in your literature review. For instance, you might explain that your review includes only peer-reviewed articles and journals.
- Standards : Description of the way in which you present your information.
- Questions for Further Research : What questions about the field has the review sparked? How will you further your research as a result of the review?
IV. Writing Your Literature Review
Once you've settled on how to organize your literature review, you're ready to write each section. When writing your review, keep in mind these issues.
Use Evidence A literature review section is, in this sense, just like any other academic research paper. Your interpretation of the available sources must be backed up with evidence [citations] that demonstrates that what you are saying is valid. Be Selective Select only the most important points in each source to highlight in the review. The type of information you choose to mention should relate directly to the research problem, whether it is thematic, methodological, or chronological. Related items that provide additional information but that are not key to understanding the research problem can be included in a list of further readings . Use Quotes Sparingly Some short quotes are appropriate if you want to emphasize a point, or if what an author stated cannot be easily paraphrased. Sometimes you may need to quote certain terminology that was coined by the author, is not common knowledge, or taken directly from the study. Do not use extensive quotes as a substitute for using your own words in reviewing the literature. Summarize and Synthesize Remember to summarize and synthesize your sources within each thematic paragraph as well as throughout the review. Recapitulate important features of a research study, but then synthesize it by rephrasing the study's significance and relating it to your own work and the work of others. Keep Your Own Voice While the literature review presents others' ideas, your voice [the writer's] should remain front and center. For example, weave references to other sources into what you are writing but maintain your own voice by starting and ending the paragraph with your own ideas and wording. Use Caution When Paraphrasing When paraphrasing a source that is not your own, be sure to represent the author's information or opinions accurately and in your own words. Even when paraphrasing an author’s work, you still must provide a citation to that work.
V. Common Mistakes to Avoid
These are the most common mistakes made in reviewing social science research literature.
- Sources in your literature review do not clearly relate to the research problem;
- You do not take sufficient time to define and identify the most relevant sources to use in the literature review related to the research problem;
- Relies exclusively on secondary analytical sources rather than including relevant primary research studies or data;
- Uncritically accepts another researcher's findings and interpretations as valid, rather than examining critically all aspects of the research design and analysis;
- Does not describe the search procedures that were used in identifying the literature to review;
- Reports isolated statistical results rather than synthesizing them in chi-squared or meta-analytic methods; and,
- Only includes research that validates assumptions and does not consider contrary findings and alternative interpretations found in the literature.

Writing Tip
Break Out of Your Disciplinary Box!
Thinking interdisciplinarily about a research problem can be a rewarding exercise in applying new ideas, theories, or concepts to an old problem. For example, what might cultural anthropologists say about the continuing conflict in the Middle East? In what ways might geographers view the need for better distribution of social service agencies in large cities than how social workers might study the issue? You don’t want to substitute a thorough review of core research literature in your discipline for studies conducted in other fields of study. However, particularly in the social sciences, thinking about research problems from multiple vectors is a key strategy for finding new solutions to a problem or gaining a new perspective. Consult with a librarian about identifying research databases in other disciplines; almost every field of study has at least one comprehensive database devoted to indexing its research literature.

Don't Just Review for Content!
While conducting a review of the literature, maximize the time you devote to writing this part of your paper by thinking broadly about what you should be looking for and evaluating. Review not just what scholars are saying, but how are they saying it. Some questions to ask:
- How are they organizing their ideas?
- What methods have they used to study the problem?
- What theories have been used to explain, predict, or understand their research problem?
- What sources have they cited to support their conclusions?
- How have they used non-textual elements [e.g., charts, graphs, figures, etc.] to illustrate key points?
When you begin to write your literature review section, you'll be glad you dug deeper into how the research was designed and constructed because it establishes a means for developing more substantial analysis and interpretation of the research problem.

When Do I Know I Can Stop Looking and Move On?
Here are several strategies you can utilize to assess whether you've thoroughly reviewed the literature:
- Look for repeating patterns in the research findings . If the same thing is being said, just by different people, then this likely demonstrates that the research problem has hit a conceptual dead end. At this point consider: Does your study extend current research? Does it forge a new path? Or, does is merely add more of the same thing being said?
- Look at sources the authors cite to in their work . If you begin to see the same researchers cited again and again, then this is often an indication that no new ideas have been generated to address the research problem.
- Search Google Scholar to identify who has subsequently cited leading scholars already identified in your literature review [see next sub-tab]. This is called citation tracking and there are a number of sources that can help you identify who has cited whom, particularly scholars from outside of your discipline. Here again, if the same authors are being cited again and again, this may indicate no new literature has been written on the topic.
