Why use a database and not OmniSearch?

  • It contains fewer types of items.  It has mostly articles and reports.
  • It is has a more focused search
    • Some databases are subject specific
    • Most databases have index terms

Benefits of Searching Library Resources

  • More items are on the college level and for college research
  • Search results can be quickly limited to... 
    • Peer reviewed (Scholarly) articles
    • a specific date or range of dates
    • Full-text 
  • Provides Citation information for a variety of guides (APA, Chicago, MLA, etc)


Link to OmniSearch


  • Searches almost everything we own
  • One stop shopping
  • Good for finding a needle in a hay stack
  • Provides citations for items found


  • Results can be overwhelming
  • Subject words are not uniform across databases
  • Finds many non-scholarly works
  • Finds more off-topic information
