Synthesizing the Work of Others.” For more information about our workshops, see Graduate Writing
Workshops.
INTRODUCTION
Compiling and synthesizing literature as a justification for one’s own research is a key element of most
academic work. Nonetheless, both the strategies and components of literature reviews vary based on
the genre, length, and prospective audience of a text. This resource gives advice on how to effectively
assess, synthesize, summarize, and make connections between a variety of sources.
THE PURPOSES OF A LITERATURE REVIEW
• To critically analyze a segment of a published body of knowledge through summary,
classification, and comparison of prior research studies, reviews of literature, and
theoretical articles
• To emphasize the credibility of the writer in their field
• To provide a solid background for a research paper’s investigation
A GOOD LITERATURE REVIEW SHOULD…
• Be organized around a thesis statement or research question(s)
• Develop your understanding of the literature in a field(s) of study
• Synthesize results into a narrative summary of what is known and not known on your
topic
• Identify areas of controversy
• Formulate questions for future research
• Be current (and historical if necessary)
5 STEPS TO WRITING A LITERATURE REVIEW
2
STEP ONE: DEFINE THE SCOPE
Look for relevant models in journals in your field (e.g., a target journal for publication) and papers,
qualifying exams, proposals, and dissertations of colleagues. While
none of these will necessarily provide you with literature relevant to
your topic, they will be good guides for scope in terms of:
1. How many papers they cite
2. Length
3. What type of information they cover
They will also be good guides for establishing the rhetorical moves that
are most relevant to your field.
Use these relevant models to determine:
1. What you are studying
2. The perspective you are taking
3. The field(s) that are relevant
STEP TWO: SEARCH THE LITERATURE
Define the Scope
Search the Literature
Analyze the Literature
Synthesize the Literature
Write the Review
3
Skim to identify relevant:
• Empirical and theoretical literature
• Primary and secondary source
• Classic and foundational studies
• Important authors who are working on your topic
Keep track of the keywords and search terms you use as well as what
databases, bibliographies, and card catalogs you searched.
Search:
• Databases
• Books
• Review Essays
• Citation Indices
• Empirical and theoretical literature
• Primary and secondary sources
• Classic and foundational studies
• Important authors who are working on your topic
TIP: Develop a system to organize and manage your
material (RefWorks, Zotero, EndNote, good old fashioned index cards, etc.).
STEP THREE: ANALYZE THE LITERATURE
As you read, ask yourself:
• What are the origins and definitions of the topic?
• What are the key theories, concepts, and ideas?
• What are the major debates, arguments, and issues
surrounding the topic?
• What are the key questions and problems that have been
addressed to date?
• Are there any important issues that have been insufficiently
addressed or not addressed at all?
TWO STAGES TO ANALYZING THE LITERATURE
SKIM AND ANALYZE
For theoretical literature, note the:
• Theorist
4
• Discipline
• Theory
• Key premises
For research-based studies, note the:
• Author
• Date of study
• Publication
• Discipline
• Methodological approach/research design
• theoretical/conceptual framework
• research (sample, site, problem, purpose, question)
• sub-questions
• key findings
• conclusions & recommendations
REPORT AND SUMMARIZE
What are the goals of summaries?
• To understand the historical context and current state of the literature
• To begin to identify themes, trends, patterns
• To begin to look for gaps and anomalies
Write out narrative summaries of the major issues, arguments, and theoretical models that inform each
piece of literature.
What types of claims do the authors make? (Fact, worth, policy, concept, interpretation).
Include conclusions that you draw from this work and any inferences you can make regarding your
study.
Try not to quote directly from the text while writing these summaries. Only quote to:
• Show that an authority supports your point
• Present a position or argument to critique or comment on
• Include especially moving or historically significant language
• Present a particularly well-stated passage whose meaning would
• be lost or changed if paraphrased or summarized
5
STEP FOUR: SYNTHESIZE THE LITERATURE
WHAT KINDS OF EVALUATION CAN I MAKE?
SUMMATIVE
When a literature review is based largely on description of what is
known (summative evaluation) the thrust is on defining and establishing
the existence of an issue or a problem with suggestions for addressing
it.
ANALYTICAL
Where the emphasis is on an investigation or analysis of the literature
(analytical evaluation) then your literature review is concentrating on
the nature of the problem, its cause and effect as a basis for action to solve it.
FORMATIVE
When a literature review emphasizes explanation of what you believe the knowledge stemming from
previous literature means (formative evaluation) it compares and contrasts the various points of view
that exist on a problem as a basis for determining which is to be preferred and what might be done to
confirm this.
WHAT KIND OF ARGUMENTS CAN I MAKE ABOUT THIS LITERATURE?
1. Argument of Discovery: a synthetic statement of what is known about your research topic
2. Argument of Advocacy: a synthetic statement of what your research/future research
aims/should aim to discover
WHAT KIND OF COMMON DENOMINATORS SHOULD I LOOK FOR ACROSS THE
LITERATURE?
• Theoretical orientations to the topic
• Qualitative versus quantitative approaches
• Methodology more generally
• Evidence
• Conclusions of authors
• Specific purpose or objective
• Chronology
HOW DO I DEVELOP AN ARGUMENT OF DISCOVERY INTO ARGUMENT OF
ADVOCACY?
• Ask, what are the implications of what is known about the research subject?
• Ask, are there gaps, omissions, debates, and questions about the topic that need further study?
6
STEP FIVE: WRITE THE REVIEW
HOW DO I WRITE THE INTRODUCTION?
1. Define or identify the general topic, issue, or area of concern,
thus providing an appropriate context for reviewing the
literature
2. Point out overall trends in what has been published about the
topic; or conflicts in theory, methodology, evidence and
conclusions; or gaps in research and scholarship; or a single
problem or new perspective of immediate interest.
3. Establish the writer’s reason (point of view) for reviewing the
literature; explain the criteria to be used in analyzing and
comparing the literature and the organization of the review
(sequence); and, when necessary, state why certain literature is not included (scope).
HOW DO I WRITE THE BODY?
What did the different ways of grouping your literature according to common denominators reveal?
Other general principles to keep in mind:
• Summarize individual studies or articles with as much or as little detail as each merits
according to its comparative importance in the literature, remembering always that space
(length) denotes significance.
• Provide your reader with strong “umbrella” sentences at beginnings of paragraphs,
“signposts” throughout, and brief “so what” summary sentences at intermediate points in
the review to aid in understanding comparisons and analyses.
HOW DO I WRITE THE CONCLUSION?
1. Summarize the major contributions of significant studies and articles to the body of knowledge
under review, maintaining the focus established by the introduction.
2. Evaluate the current “state of the art” for the body of knowledge reviewed, pointing out major
methodological flaws or gaps in research, inconsistencies in theory and findings, and areas or
issues pertinent to future study
3. Conclude by providing some insight into the relationship between the central topic of the
literature review and a larger area of study such as a discipline, a scientific endeavor, or a
profession.
OTHER CONSIDERATIONS AND TECHNIQUES FOR WRITING A
LITERATURE REVIEW
VERB TENSE
7
Technique Examples and Common Uses
Using past tense emphasizes the researcher’s
agency.
Examples: Jones (1997) investigated the causes of
illiteracy; The causes of illiteracy were
investigated by Jones (1997).
Common uses: reference to single studies; focus
is on what previous researchers did
Using present perfect does not emphasize the
researcher as agent.
Examples: The causes of illiteracy have been
widely investigated (Jones 1977, Ferrara 2000,
Hyon 2004); There have been several
investigations into the causes of illiteracy (Jones
1977, Ferrara 2000, Hyon 2004); Several
researchers have studied the causes of illiteracy
[1-3].
Common uses: reference to areas of inquiry;
focus is on what previous researchers did
Using present tense does not refer to researcher
activity at all.
Examples: The causes of illiteracy are complex
(Jones 1977, Ferrara 2000, Hyon 2004); Illiteracy
appears to have a complex set of causes [1-3].
Common uses: reference to the current state of
knowledge; focus on what has been found
In general, moving into the present perfect and then into present tense indicates that the ideas being
reported are increasingly close to the writer’s in some way: close to the writer’s own opinion, or close
to the writer’s own research, or close to the current state of knowledge.

if the author had related the findings to previous
work in the topic.
It would have been better if the authors had
given their main findings in the form of a table.

Despite the many interesting citations in support
of his view, the citations are dated and are not
likely meaningful today.
PARAPHRASING RESEARCH BY OTHERS
• When reading a passage, try first to understand it as a whole, rather than pausing to write
down specific ideas or phrases as you read.
• Be selective. Unless your assignment is to do a strict, “literal” paraphrase, you usually don’t
need to paraphrase the entire passage. Instead, summarize only the material that helps you make
your own point.
• Think of what “your own words” would be if you were telling someone who’s unfamiliar with
your subject (your mother, sibling, friend) what the original source said.
• Remember that you can use direct quotations of phrases from the original within your
paraphrase. When reusing shared language (common phrases within the discipline), you don’t
need to change the phrasing or use quotation marks.
CLAIMING CENTRALITY FOR YOUR RESEARCH
USE QUASI-NEGATIVE SUBJECTS
• Apart from a chapter in Foster (1997), this series has been little discussed by critics or art
historians. For example, these pictures were ignored by Johns in her…
• Little is known, however, about participants’ views of university-community collaborations.
USE CAUTION WHEN USING “NO” OR “NONE”
• You can use “no” when your conclusion is based on but does not directly refer to the cited
literature.
• If you want to refer directly to the previous research, use none of.
OTHER COMMON STRATEGIES
• The research has tended to focus on… [this], rather than on… [that]
• These studies have emphasized… [this], as opposed to… [that]
9
• Although considerable research has been devoted to… [this], rather less attention has been
paid to… [that]
PARTICULARLY USEFUL FOR STEM FIELDS
• However, it remains unclear whether…
• It would thus be of interest to learn how…
• If these results could be confirmed, they would provide strong evidence for…
• These findings suggest that this approach might be less effective when…

• Such active-R networks eliminate the need for any external passive reactance elements. This
paper utilizes the active-R approach for the design of the circuit…
IT MAY BE MOST EFFECTIVE TO COMBINE APPROACHES
• Previous research has not addressed whether or not people who are employed in some
occupations rate the maintenance of overall appearance more important than do people who
are employed in other occupations. Moreover, research has not fully considered the
behavioral consequences of individuals putting more or less emphasis on physical appearance
(e.g., does it affect grooming habits or maintenance rituals?). Nor has it addressed if they
patronize a beauty shop, a barber shop, or a beauty salon.
EVALUATING YOUR LIT REVIEW
STRIKE & POSNER (1983) SUGGEST A GOOD LITERATURE REVIEW HAS THREE
CHARACTERISTICS:
1. It clarifies and perhaps resolves problems within a field of study rather than glossing over
those problems
2. It results in a “progressive problem shift” that yields a new perspective on the literature
with more explanatory and predictive power than is offered by existing perspectives
3. It satisfies the formal criteria of a good theory (consistency, parsimony, elegance, and
fruitfulness)
HART (1998) SUGGESTS THE READER WILL LOOK FOR EVIDENCE THAT:
• You have a clear understanding of the topic
• You have identified all major studies related to your topic
• You have drawn appropriate conclusions from prior research
• You have established and described the various points of view related to your topic
10
• You are proposing valid recommendations based on analysis of the information contained in
your sources
• You have demonstrated that there is a genuine research issue to be addressed.
