Answer
While some people may use the terms peer-reviewed and scholarly interchangeably, they are not always necessarily the same. All peer-reviewed resources are scholarly, but not all scholarly resources are peer-reviewed.
Scholarly resources are written by experts in the field, with an academic audience in mind. The peer-review process involves sending an article to multiple other experts in the field to verify the accuracy of the information. Peer-reviewed articles are held to a high standard in academia due to the extra steps taken to verify the information.
Many scholarly journals require peer review, however, not all do because of the time and money involved in having articles peer-reviewed. Certain resources, such as textbooks, dissertations, and theses, are typically not peer-reviewed but are still considered scholarly and valid sources.
When you search in EagleSearch, you can use the filter Peer-Reviewed (Scholarly) to narrow down to peer-reviewed resources. This filter shows only peer-reviewed resources but includes the term scholarly because of how commonly the terms are used interchangeably.
