1. Identify key terms
• 3-4 keywords
• Your tool during the search process
• How to identify them?– Working title of your project– Research question– Keywords of previous studies similar to yours– Subject headings within electronic databases
Key terms
• Pay attention to:– English vs American spelling:
Orthopaedic - Orthopedic
– All possible terms:Cancer - Malignancy - TumorFracture - Trauma - Injury
2. Locate the literature(Discipline-based)
• Sources:– Primary sources: primary studies, dissertations– Secondary sources: systematic reviews, review
articles, textbooks, encyclopedia
• Technique:– Manually: books, old articles– Electronically: databases, conference proceedings
Databases
• Depends on your discipline (so we cannot cover it all tonight)
• In Medicine: MEDLINE, EMBASE
• ProQuest: to search all MSc & PhD theses
• Google Scholar: fits all (poor man best friend)
Broad Term Lots of irrelevant results

5 Steps of Literature Review
1. Identify key terms2. Locate the literature3. Critically appraise & select the literature4. Organize the literature5. Write the literature review
3. Critically appraise & select the literature
• For each piece of information (article, book, thesis), you have to decide:– Is it valid & accurate?– Is it relevant to your study?
• If in doubt, get it in– It is easier to remove this source later than to find it
4. Organize the literature
• The most critical step – otherwise, you will be overwhelmed
• Filing: photocopies, downloads– By Author Name & Year (there are other ways)
• Abstracting (systematic note taking):– For each source, write YOUR words on the research
problem, question, instruments & results– Copying the abstract plagiarism
• Draw a map of your literature!

5. Write the Literature Review
• Plan enough time
• Draft (Revision Read Revision)3
• Think about:– Content– Organization– Writing & Citation Style– Spelling & Grammar
Content
• Do not list studies
• You are presenting a summary AND an argument using your analysis of the literature
• How much to write?– Balance DEPTH & BREADTH– It depends on what for– For grant proposal: 8-10 double-spaced pages– For PhD Thesis: ? 40-50 pages
Content
• Smooth logical transition of ideas
• Current & relevant literature
• Unbiased discussion (strengths & weaknesses) of supporting & opposing studies
• Consistent referencing style
Organization of Literature Review
Introduction
Body
Conclusions• Summary• Implication• Suggestion for future research
• Background• How is it organized
• Different styles: themes, chronological, debate
• Smooth transition• Not a list of studies• It is an argument
Plagiarism
• Copying without citing
• Paraphrasing without citing
• Using other’s ideas without citing
By the end of the literature review, your goal is to have
1. High Quality Research Proposal:– Covered the subject thoroughly & succinctly– Addressed gap/uncertainty– Justified your hypothesis & instruments
2. High Impact Research Proposal:– On the institution and/or society– On the scientific community– On the Kingdom
3. High Potential for Success:– Experience of the research team– Reasonable allocation of time, resources, rules
