Why a literature review
 Provides a rationale for your research
question
 Provides a frame of reference for your
research project

More specifically…
 A literature review should answer the
following questions:
| What is known/understood?
| What are the strengths and weaknesses of present
knowledge and understanding?
| What is not known?
| Where are the gaps in knowledge?
| What is needed to be studied to improve knowledge and
understanding?
| What theories can frame the approach to study of the topic?

Lit review vs. essay
 Essay
| An essay focuses on a topic and uses the literature as a
support for the arguments.
 Literature Review
| In a standalone literature review, the literature itself is the
topic of discussion and evaluation. You draw connections and
comparisons of the included studies. You evaluate and
discuss not only the informational content, but the quality and
limitations of the content.

Getting Started
 Find out what information is available
| OMNI
| PubMed
| Your favourite search tool
 Do some background reading
| Find a review article
• Use a database filter (Pubmed, Scopus, WoS)
• Use review as a search term
| Find a book
• Look at the Table of Contents
| Find an encyclopedia entry
• Often provide background readings

Map your topic
 Think of the landscape of your topic
 Outline the various aspects/concepts/main
ideas

An Example of Concept Mapping

or it might look like this...
 or

Narrowing your topic
 Pick one or two aspects to focus on
 Go deeper into these areas
 Think of questions about these aspects
| What population do you want to study?
| What is the relationship between an issue/intervention and a
particular outcome?
| What is the relationship between an independent variable
and a particular dependent variable?

Example: AIDS in Africa
 Malnutrition
| What impact does AIDS have on malnutrition?
| What is being done to combat this issue?
| Are theses interventions effective?
| What more can be done?
 Poverty
| What is the relationship between AIDS and poverty?
| What other factors are involved?
| What programs exist to tackle this problem?
| Why do certain programs/interventions work and others not?
 Orphans
| How has AIDS affected children of parents with AIDS in Africa?

Identify Search Terms
 Concepts/main ideas
 PICO
| Population
| Intervention
| Comparison
| Outcome
 Related terms
 Controlled vocabulary

Combining Search Terms
 Boolean operators – AND, OR, NOT
 Phrase searching – “…”
 Truncation - *
 Proximity operators – N/x, NEARx

 AIDS in Africa
| (AIDS or “acquired immune deficiency syndrome” or HIV)
| (Africa or Sub-sahara* or Burundi or Malawi or ….)
| (Child* or youth)
| orphan*
| (Malnutrition or “nutritional deficiency” or malnourishment)
| (Poverty or “low income” or poor)
 You may need to do separate searches for
different aspects of your topic

Where to look
 Think about who/what is interested in the
topic
 Think about what subject area might
cover this topic

 African governments
 NGOs
 AIDs researchers
 Economists
 Nutritionists

 WHO
| IRIS Digital Library
| Health Topics
 PubMed
 CINAHL
 Worldwide Political Science Abstracts
 World Bank
 Government Info

Data and Statistics
 Data
| Canada
• ODESI
| WHO
• Data and statistics
| United Nations
• UNdata
| OECD
• OECD.Stat

Keeping it all organized
 Citation Management
| Mendeley
| Endnote
| Zotero

Note Taking
 Underline
 Highlight
 Take notes in your own words

Summary vs Synthesis
Summary
 A summary is a brief
statement of a
source(s)
 In order to synthesize several sources you should first summarize each
source individually
Synthesis
 An integrated essay
based on multiple
sources

Critical Analysis
 Significance
| Your interpretation of the impact of this study
 Evaluation
| Is the study design suitable?
| Was the sample size/population appropriate?
| Do the results support the conclusions?
| Has the study cited the appropriate literature?
| What are the limitations of the study?
 Relevance
| How is this relevant to your research?
| Does this agree/disagree with other sources?
| Does this add something new to your research?

Synthesize – organization
 Sequential
| Show progression of the field/topic….
 Topical
| Topic 1 with subtopics, topic 2 with subtopics….
 Methodological
| No other method has proven….
 Theoretical
| Contrast and compare theories….

Identify Common Themes
 Hypotheses
 Populations studied
 Theories
 Methods
 Outcomes

Contrast and Compare
 He said/she said
| Do different studies agree or disagree
| Do they agree on some things but disagree on others

Identify Gaps
 What is missing?
 What can be studied next?

Writing and Reading
 ‘Writing while you collect and collecting
while you write.’ Wellington et al (2005)
| The writing stage is part of the research process, not
something that happens after you have finished reading the
literature.
| Once you are part way through your reading you can have a
go at writing the literature review.
| It is often not until you start explaining something in writing
that you find you need to collect more information.

Introduction
 Define the topic -WHAT
 Purpose - WHAT
 Rationale - WHY
 Scope – WHAT, WHEN
 Structure - HOW

When to stop
 ‘Build an [argument], not a library’ (Rudestam
and Newton (1992)
| Keep your research focus in mind, don’t stray
| Create an outline and stick to it
| As you read, ask yourself these questions:
• Have I answered my question without any obvious gaps?
• Are no new related issues coming up as I search the literature?
• Have I found multiple references which cover the same material
or just enough to prove agreement?

Proofreading and editing
 Write a draft
 Let it sit
 Look at it with fresh eyes
 Ask your ____ to read it

Checklist
 Have I:
| outlined the purpose and scope?
| identified appropriate and credible (academic/scholarly) literature?
| recorded the bibliographical details of the sources?
| analysed and critiqued your readings?
| identified gaps in the literature and research?
| explored methodologies / theories / hypotheses / models?
| discussed the varying viewpoints?
