  22. MeSH • Medical Subject Headings • Subject terms assigned to articles by PubMed indexers, specialists who read article • Highly specific—over 26,000 terms • Excellent way to search PubMed • But…MeSH only works for citations that have been indexed, so you will miss some citations searching with MeSH

  32. A Few Extra Search Tricks

  33. Boolean Searching • Based on mathematical logic • Uses the words AND, OR, and NOT to connect search terms • These words (Boolean operators) can either limit or expand your search

  34. Boolean Searching Using AND

  35. Boolean Searching Using OR

  36. Boolean Searching Using NOT

  37. Truncation • Shortcut for finding all forms of a word • PubMed uses the asterisk character (*) for truncation • Nurs* would find nurse, nurses, nursing….. • Expands search • Be careful! Truncation turns off automatic term mapping in simple search—check search details!

  38. Proximity Searching • Searches for words adjacent to each other • PubMed only allows for exact phrase searching—words next to each other in exact order • Use quotation marks to enclose search phrase—”Endonasal activity in WG is associated with”

  49. Managing Citations

  50. Managing Citations • Clipboard holds information for 8 hours • Clipboard best for short sessions • My NCBI provides permanent storage of citations • My NCBI has many other helpful personalization features • My NCBI very useful if use PubMed regularly or for big projects
