Research Tips: Using

Why use limiters (filters)?

Most databases allow you to narrow your search results according to certain criteria.

Common limiters (also called filters) include:


Limiters vary by database.

Please check the database's Help page, for specific information.

Full Text

Do not use the Full Text limiter!  It prevents you from finding the full-text articles that are available in our other databases or subscriptions. 

Use the Find-It link  located next to the abstract to find the full-text article in our other resources. For detailed instructions on finding full-text articles, go to the Find Full-Text tab.

Peer-Reviewed Journals

Some databases allow you to limit to articles from peer-reviewed journals.

Peer-reviewed journals are publications that include articles that have been reviewed by acknowledged experts in the field of study covered by the journal.


Look for a check box on the search page that will limit to peer-reviewed journals.




If the database does not offer a peer-reviewed limiter, use Ulrichsweb to determine if the journal is peer reviewed.

Publication Date

Look for a date limit on the search page. These are usually free-text boxes or drop down menus.
