What is a Literature Review?
• an overview of previous research on your research topic
• a comprehensive review of all published research that is relevant to your proposed investigation and guided by your research objectives

Questions to Keep in Mind:• What is known about the subject?• Are there any gaps in the knowledge of the subject?• Have areas of further study been identified by other researchers that you
may want to consider?• Who are the significant research personalities in this area?• Is there consensus about the topic?• What aspects have generated significant debate on the topic?• What methods or problems were identified by others studying in the field
and how might they impact your research?• What is the most productive methodology for your research based on the
literature you have reviewed?• What is the current status of research in this area?• What sources of information or data were identified that might be useful to
you?

Purpose of a Literature Review• Convey the depth and breadth of research that
has been accomplished on a subject• Supports the motivation and significance of the
research• Identify important issues and link to hypotheses• Identify key areas of missing knowledge• Describe methodologies used• Describe existing data sets• Link proposed research to previous and ongoing
research efforts -- provide context

Purpose of a Lit Review
• Helps you learn everything about your subject
• Ensures that you are not “reinventing the wheel”
![Page 6: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/6.jpg)
How to do a Literature Review?
• Define the topic
• Compile and prioritize a list of keywords
• Identify sources of information
• Read, evaluate, analyze all the works
• Discuss findings and conclusions with others -- important for understanding context, gaps in previous research
• Divide works into supportive and antithetical positions
• Identify relationships between works in the literature
• Articulate how these apply to your research

Identify Resources
• Books• Journals• Conference Papers• Dissertations• Bibliographies• Maps• Internet• Indexes/Abstracts Printed• Electronic Databases• Government publications• Theses• Interviews and other unpublished research
![Page 8: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/8.jpg)
Assessment
• Assess the quality of the information source:– refereed journal article?
– conference proceedings?
– corporate report?
• Assess the standing of the author– academic?
– journalist?
– government employee?
– is the work in their major field of research?
![Page 9: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/9.jpg)
Evaluate the Information
• determine the facts/points of view• examine new findings• question assumptions• determine if methodology is appropriate• are the objectives outlined clearly• do the conclusions logically follow from the
objectives?• identify classic, “landmark” articles

Continually Evaluate Your Research Process
• No relevant information?– Need to reconsider your search strategy– New keywords– Explore other disciplines for information
• Too many irrelevant items?– Re-evaluate keywords – Narrow scope of your search
• Document your search strategy – Keep multiple lists of keywords– Indicate what works, what doesn’t

Getting the Information
• Download full text from the Internet
• University library
• Interlibrary loan
• Government offices
• Specialty libraries

Information Management
• Select a strategy for organizing information– Notecards (primitive but it works!)
– List of references on a computer
– Bibliographic database software (EndNote)
• Develop good lit search habits– Start immediately
– Keep searches up to date
– Summarize papers that you read
![Page 13: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/13.jpg)
The Annotated Bibliography
• “A bibliography in which each citation is followed by an annotation containing a brief descriptive and/or evaluative summary, synopsis, or abstract.”
–www.farmingdale.edu/library/gloss.html
• Good tool for quick summarization, assessment– “Keeps you honest”
• Great way to share this stage of your progress– See Erik Stemmerman’s site!– GEO 565

Annotated Bibliography vs. Lit Review
• Annotated bibliography is basically a set of notes on each reference
• Lit review flows in scientific/technical style
• Lit review compares/contrasts/links various references and is far more analytical
![Page 20: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/20.jpg)
Writing the Literature Review
• Break the review into thematic sections
• Prioritize the sections
• Maintain focus– relate literature to your research hypotheses
![Page 21: Literature Reviews: the Hows, Whys and Wherefores GEO 518 Anne Nolin and Dawn Wright](https://reader035.vdocuments.net/reader035/viewer/2022062519/56649eef5503460f94bff174/html5/thumbnails/21.jpg)
Literature Review Style• Document every statement of fact• Use scientific/technical style:
– use 3rd person– follow citation style of foremost journals and other
theses/dissertations– no jargon– smooth transition between sections
“Smith (1999) asserted that…”“Yosida (1961) found that…”“In early work, Conti (1953) suggested that…”“blah blah blah (e.g. Rangel, 1998; Mason, 2003)”
