Using Limits in Your Search

What are limits and why use them?

Limits are helpful in focusing your search.  Once you've done your initial search you can use some limits to help you narrow your results to a more manageable amount of information.

  • Date:  limit results to a specific time frame
  • Peer review:  limit to only peer-reviewed articles
  • Full text:  find only the articles available in full text  **TIP:  you can request an article that isn't available through Interlibrary Loan
  • Publication type:  limit results to meta analysis, reviews, systematic reviews, research articles, and evidence based practice.
