Where to Search

Basic Search Tips

  • Divide topic into key concepts
  • Convert concepts to search terms (subject terms and keywords).  In PubMed, use MeSH terms (medical subject headings).
  • Search concepts individually, then combine using Booleans (and, or, not)
  • Apply limits such as date of publication, type, language, age groups
  • Focus search with limits (age groups, publication types, human/animal ...)
  • Manage results with MyNCBI, EndNote, or similar reference management programs
