where to search
Where to Search
  • Primary Sources
    • Computerized structured databases
    • Manual
      • Cumulative indices
      • Journal indices
  • Secondary Sources
    • Library ‘Card Catalog’
    • Books in Print
    • WWW Search
structured databases using controlled vocabularies
Structured Databases(Using Controlled Vocabularies)
  • Journal Articles (use specific database’s terms index)
    • MEDLARS: Medical Subject Headings (MeSH)
    • CINAHL: subject heading tree/permuted index
    • Excerpta Medica (Embase): EMTREE
  • Books and Monographs:
    • library cataloging system ( Dewey, NLM, LoC)
medical subject headings mesh
Medical Subject Headings (MeSH)
  • The MeSH Supplement to Index Medicus® (alphabetical and hierarchical listing of terms)
  • The MeSH Annotated Alphabetic List (an alphabetic listing includes notes/ historical info)
  • The MeSH Tree Structures (a hierarchical listing)
  • The Permuted MeSH (a listing of each significant word or root appearing in any MeSH heading)
  • NLM’s Online MeSH Browser
  • Key Term Mapping/Translation (e.g., OVID)
example chest x rays
Example: ‘Chest X-Rays’

“Chest x-rays" not a MeSH term

boolean or
Boolean ‘OR’


Example: “asthma OR exercise” yields pages that include either word; e.g., aerobic exercise and atopic asthma

boolean and
Boolean ‘AND’




Example: “asthma AND exercise” yields pages that include both words

boolean not
Boolean ‘NOT’


Example: “asthma NOT exercise” yields pages that include asthma but not exercise

internet directories
Internet Directories
  • Provide categorized lists of Web sites, constructed by humans (professional and/or volunteer editors)
  • Tend to be selective rather than all-inclusive (most aim for quality over quantity)
  • Usually include searchable database containing descriptions of the directory’s Web sites
  • Require some knowledge of subject matter
  • Some categories can quickly become outdated

Internet Directories
  • General Directories, e.g.Yahoo!
  • Medical Directories (Examples)
      • Medscout
      • Galaxy Medical List
      • Achoo
      • MedWeb
      • Hardin MD
search engines
Search Engines
  • A computer-generated index of all the infor-mation found on all searched Web pages
  • Aims to include all Web pages that contain the information, but without assessing quality
  • Takes you to the exact page on which the words you are looking for appear
  • Regularly updated by automated processes
