Look up these four titles in Mirlyn and evaluate whether the publication is peer-reviewed
Scholarly works are often challenging reads for members of the general public, since the articles are written with a certain expectation that the readers are somewhat familiar with the concepts and terminology contained within the articles.
Sometimes it can be difficult to tell whether a publication is peer-reviewed. Many databases (indexes) will allow you to limit your search results to peer-previewed titles, but others do not.
Ulrich's Periodicals Directory is an online tool that will allow you to verify whether a title is peer-reviewed.
Just do a title search for the questionable title in Ulrich's. If you see a little referree icon "" next to the title, then you can rest assured that the publication is peer reviewed. However, use your best judgement if you question whether a source is peer-reviewed. Certain documents in peer-reviewed publications (such as book reviews and letters to the editor) are NOT peer-reviewed, even if the publication iteself is designated as peer reviewed.
