tips and tricks for searching pubmed
Tips and Tricks for Searching PubMed
  • Truncate (stem words) with an asterisk (*)  neur*Note: this turns off automatic term mapping (ATM) to MeSH terms
  • Use Limits tab to restrict search to an author, journal, range of years, type of article (e.g., review articles)
  • Use Details tab to see the behind the scenes search (ATM) that was performed if search for nerve cells, PubMed searches for that, but also NEURONS
  • To search for a phrase, enclose words in quotation marks. However, this will turn off ATM  “nerve cells”
pubmed vs google scholar
Indexed by human experts

Searches default fields (e.g., title, author, etc.)

Easily find what journals are indexed (affects ‘cited by’, what time frame covered

Controlled vocabulary (subject headings) which can be utilized for searching

Can select and work with MANY citations at a time

Know which journals it indexes

Uses automated extraction of information from text and citations

Searches full text – may need subscription to read articles

Don’t know what journals are being searched (affects ‘cited by’), what time frame covered.

No controlled vocabulary (subject headings)
