In Ebsco databases and library one search, there are limiters available to use.
All filters will provide a chance to use all available filters. This is good for limiting by language, content provider, subjects, and more! See the full screenshot below.
Academic Peer-Reviewed -Limit to article published in academic/peer-reviewed or scholarly fournals
All time - limit by publication date
Source types - find specific types of sources (i.e. magazines, trade publications, news, and more).
Proquest databases, such as ABI Inform, Gender Watch, and Proquest Disserations have their limit options on the side of the page. Consisdering using subjects to help you refine your searches.
