SELECTION OF TOPIC
FOR LITERATURE REVIEW
How To Select a Topic and Write A
Literature Review
 Definition of a Literature Review
• A literature review
 surveys scholarly articles, books and other sources
(e.g. dissertations, conference proceedings) relevant
to a particular issue, area of research, or theory.

 provides a short description and critical evaluation of

work critical to the topic.

 offers an overview of significant literature published

on a topic.

(Lyons, 2005)
Literature Reviews are Conducted For
Various Reasons:
1. For a review paper

2. For the introduction (and discussion) of a research

paper, masters thesis or dissertation

3. To embark on a new area of research

4. For a research proposal

(Burge, 2005)
 Conducting a literature review
will help you:
• Determine if proposed research is actually needed.
 Even if similar research published, researchers might
suggest a need for similar studies or replication.

• Narrow down a problem.

 It can be overwhelming getting into the literature of a field of
study. A literature review can help you understand where
you need to focus your efforts.

• Generate hypotheses or questions for further studies.

(Mauch & Birch, 2003)

 Conducting a literature review
will give you:
• Background knowledge of the field of inquiry
 Facts
 Eminent scholars
 Parameters of the field

 The most important ideas, theories, questions and

hypotheses.
• Knowledge of the methodologies common to the
field and a feeling for their usefulness and
appropriateness in various settings.

(Mauch & Birch, 2003)

 Outline of Review Process
• Formulate a problem - which topic or field is being
examined and what are its component issues?

• Search the literature for materials relevant to the

subject being explored.
 searching the literature involves reading and
refining your problem

• Evaluate the data - determine which literature makes a

significant contribution to the understanding of the topic

• Analyze and interpret - discuss the findings and

conclusions of pertinent literature

• Format and create bibliography

(Lyons, 2005)
 TIPS ON FORMULATING A
PROBLEM

 Select a topic you are interested in

 You want to be fascinated throughout the process and less likely to lose motivation.

 Choose a topic with a feasible focus.

 Keep the focus clear and defined and it will be easier to complete than something
huge like "headaches“

 Get Help - get it early and often.

 Solicit opinions before you begin, review drafts once start them

 You may want to start out with a general idea, review the literature of
that area, and then refine your problem based on what you have found.

(Green, Johnson, & Adams, 2006)

 The “Literature” in the Review

• The literature included can be any format appropriate to your topic.

• Don’t restrict yourself to journal articles.

 Look in books – you’ll need to know and cite the work of
major contributors to the field. A lot of this in books,
especially annual reviews
 Important Information can be found in reports,
conference proceedings, and other non-journal sources.
Search government websites and associations related
to your topic.

• Look at library subject guides in your area to find the key databases
additional resources
LITERATURE SEARCH
 Perform a preliminary search of the literature.
 Search lit to see what other work in the area of interest has
already been published.
− Gives a preview of the number of articles available on the topic.
− If your topic is already written about, select a slightly different topic or
modify the focus of the objective.
 Recent journal issues in areas central to the topic may provide
leads to content that should be in the review.
− Consult Web of Science’s Journal Citation Index for an idea of the most
important journals in the field
 Develop a list of subject headings that relate to themes of
interest
LITERATURE SEARCH

 Search across multiple databases and information resources.

− It’s not adequate to use Medline as your one and only resource

 Read the literature throughout the search process.

− What you read will guide your subsequent searches and refine your topic.

 Your search should help refine the topic and objective of the
overview being written.
THINK AHEAD

 The more one learns about a subject, the more questions come
to mind.
 Keep a list of questions and hypotheses that come to your mind
or that are mentioned in what you read.
 These questions will help guide you when you are constructing your review

 The questions will also guide you in discussing the implications of your own
findings and the additional research directions your work supports or
suggests.

(Mauch & Birch, 2003)

SAVE YOUR REFERENCES

• Keep a record of the literature you collect

• Record where and when you retrieved the information

• Use a citation manager program like RefWorks

or EndNote

• Better to record too many references than

have to return a few weeks or months hence
and spend hours trying to relocate documents
DATA EVALUATION: SELECTING
LITERATURE
 Read widely
 When you read for your literature review, you are actually
doing two things at the same time:
1. Trying to define your research problem: finding a gap, asking a
question, continuing previous research, counter-claiming
2. Trying to read every source relevant to your research problem

• It is usually impossible to do the latter

− you will need to identify the most relevant and significant works and focus
on them.

(Asian Institute of Technology)

DATA EVALUATION: SELECTING
LITERATURE

 As you define your problem you will more easily be able to

decide what to read and what to ignore.
 Before you define your problem, hundreds of sources will seem
relevant.
 However, you cannot define your problem until you read around your
research area.
 This seems a vicious circle, but what should happen is that as you read
you define your problem, and as you define your problem you will
more easily be able to decide what to read and what to ignore.

(Asian Institute of Technology)

HOW TO READ THE MATERIAL

• Reading for the big picture

 Read the easier works first

 Skim the document and identify major concepts

 After you have a broad understanding of the

10 to 15 papers, you can start to see
patterns:
− Groups of scientists argue or disagree with other groups. For
example, Some researchers think x causes y, others that x is only a
moderating variable

(Carroll, 2006)
NARROW YOUR FOCUS
 Start from new material to old, general to specific
 starting with general topic will provide leads to specific areas of interest and help develop
understanding for the interrelationships of research

 Note quality of journal, output of author

 As you read and become more informed on the topic, you will probably
need to go back and do more focused searches

 Think, analyze, and weed out

 Arrange to spend some review time with an experienced researcher in the

field of study to get feedback and to talk through any problems
encountered

(Mauch & Birch, 1993)

READ THE MATERIAL CLOSER
 Step 1: read the abstract
 Decide whether to read the article in detail
 Step 2: read introduction
 It explains why the study is important
 It provides review and evaluation of relevant literature

 Step 3: read Method with a close, critical eye

 Focus on participants, measures, procedures
 Step 4: Evaluate results
 Do the conclusions seem logical
 Can you detect any bias on the part of the researcher?

 Step 5: Take discussion with a grain of salt

 Edges are smoothed out
 Pay attention to limitations

(Carroll, 2006)
 ANALYZE THE LITERATURE
 Take notes as you read through each paper that will be included in the review

 In the notes include:

 purpose of study reviewed
 synopsis of content
 research design or methods used in study
 brief review of findings

 Once notes complete organize common themes together. Some people do this in a word
document, others use index cards so they can shuffle them.

 Some people construct a table of info to make it easier to organize their thoughts.

 As you organize your review, integrate findings elicited from note taking or table making
process.

(Green, Johnson, & Adams, 2006)

QUESTIONS TO CONSIDER IN YOUR
REVIEW
•What do we already know in the immediate area concerned?
•What are the characteristics of the key concepts or the main factors or
variables?
•What are the relationships between these key concepts, factors or
variables?
•What are the existing theories?
•Where are the inconsistencies or other shortcomings in our knowledge
and understanding?
•What views need to be (further) tested?
•What evidence is lacking, inconclusive, contradictory or too limited?
•Why study (further) the research problem?
•What contribution can the present study be expected to make?
•What research designs or methods seem unsatisfactory?

(Asian Institute of Technology)

 Construct the Literature Review
• In the introduction, explain why the topic is important and give the
reader an idea of where you are going in your paper.

• Group research studies and other types of literature according to

common denominators.
 If you’ve taken notes before, the common themes are
more easily identifiable.
 Some factors used to organize reviews are:
− Conclusions of authors
− Specific purpose
− Objective
− Chronology (this method will give the worst
impression, use only if it really makes sense to your
topic!)
(University of Wisconsin, 2006)
 Construct The Literature Review
• Summarize individual studies or articles
 Use as much or as little detail as each merits according to its comparative
importance in the literature
 Space (length) denotes significance.
 Don’t need to provide a lot of detail about the procedures used in other
studies.
 Most literature reviews only describe the main findings, relevant
methodological issues, and/or major conclusions of other research.

• Discuss major areas of agreement or disagreement

• Tie the study into the current body of lit, make logical interpretations
from the lit reviewed.
 If there is no discussion of the relevance of the overview to other work in
the field, or if there is no interpretation of the literature, it may signal the
author has not thoroughly investigated the topic.

(University of Wisconsin, 2006)

 Organization of the Review
Introduction to the lit review
 Content - what is covered
 Structure - how it is organized
 Boundaries - what is outside of its scope

Body of the Lit Review

SECTION 1 SECTION 2 ADDITIONAL SECTIONS
The most important topic or a key concept The next most important  Follow the same
 discussed and evaluated topic or a key concept pattern
 summarized and related to your research  discussed and evaluated
project  summarized and related
to your research project

Conclusion
From each of the section summaries,
 highlight the most relevant points
 relate these back to the need for research
 reiterate what these mean for the research
design

(Golden-Biddle & Locke, 1997)

 An Effective Literature Review
• Places each work in the context of its contribution to the
understanding of the subject under review
• Describes the relationship of each work to the others under
consideration
• Identifies new ways to interpret, and shed light on any gaps
in, previous research
• Resolves conflicts amongst seemingly contradictory previous
studies
• Identifies areas of prior scholarship to prevent duplication of
effort
• Points the way forward for further research
• Places one's original work (in the case of theses or
dissertations) in the context of existing literature
(Lyons, 2005)
BE ACCURATE AND THOROUGH
• Your review acts as a guide of your topic for others.
• Take care to make your review:
 Accurate: e.g., Citations correct, findings attributed to authors
correct.
− Make sure someone can track down
the article and that you have provided
a reliable representation
 Complete: i.e., include all important papers
(not every paper written on the topic).
RESEARCH TIPS

 Use the A-Z guide to find key databases and other resources related to
your topic
 Consult with a librarian for resource recommendations and how to use
them.
 Talk to experienced researchers in the field, they can recommend
resources and identify key works and authors
 Look at reviews in completed dissertations and reports from your
program to get an idea of the format and requirements
 When collecting references, use a citation management tool like
RefWorks or EndNote
