About Limiters

Limiters are search tools available on the results page that allow researchers to narrow down their searches based on such options as:

  • whether a source should be peer-reviewed,
  • what the format of the source should be (e.g., book or journal),
  • the date or date range of the publication,
  • the language in which the source is written.

In a database, limiters tend to be below the search box(es) or in the left margin once and initial search has been conducted. If you do not see limiter options on a database search page or on a results page, look for an "advanced search" or "modify search" link.

Limiters Example

In the example, a search has been conducted for Instacart AND "gig workers". On the left, you can see the limiters, which allow for selecting articles that are full-text or peer reviewed; the date and date range; the source type; and many others.

A search result screen in the ABI/INFORM collection database for instacart AND “gig workers.” The left hand side of the screen displays a list of limiters including items like publication date and source type.
