A thorough review of the literature includes:

• Searching multiple databases
• Using synonyms, related terms, and controlled vocabulary (e.g. MeSH terms/headings) in addition to your topic keywords
• Searching concepts separately to reveal limiting variables
• Combining concepts strategically to focus results without over-narrowing
• Using database limiters/filters thoughtfully
• Applying inclusion/exclusion criteria as you skim result lists 
• Scheduling a research appointment to brainstorm search options with your Personal Librarian

More Databases:

Productive and effective searching:

• Start with one or two keywords 
  • Add terms with AND to narrow results (hypertension AND music)
  • If needed, combine synonyms with OR to include related terms (alzheimer's OR dementia)
• Review results to brainstorm additional or alternate keyword options
• Try multiple searches with different keywords and explore more than one database
• Apply limiters thoughtfully
  • After seeing how productive your keywords are, limit by date range and English language
  • Other limiters to try:
    • Peer Reviewed (articles must be approved by other scholars before publication)
    • Other database-specific limit options (age range, type of study, etc.)
