A scholarly journal is peer-reviewed when manuscripts are sent to experts in the related field during the publication process. Sometimes the manuscripts are sent anonymously (blind peer-reviewed). The experts make recommendations to the editor for publication, rejection or revision. These journals are generally thought to be of the highest quality.
To limit the result list in a DATABASE to only articles published in Peer Reviewed journals under "Refine Results" select the limiter "Peer Reviewed."
To find out if a journal is peer reviewed, search for the journal in the database Ulrichsweb.
For best results search by ISSN instead of title. Every publication has a unique ISSN number whereas there can be multiple publications with the same title. You can find the ISSN in the journal or article record.

If you click on the journal title you will find a basic description of the journal including details such as the name of the publisher, and whether the publication is peer reviewed.
