To find out if a journal is peer-reviewed, try the following:
Note the 'Refereed' symbol.
Hint: A common mistake is to think that Ulrichsweb will provide you with the articles from the journal. This is not the case! It is a great resource letting you know all about the journal, but not the contents of the journal.
Most databases allow you to limit to peer reviewed, either by selecting an option before searching, or from the results screen.
For example, EBSCO Discovery Service (EDS) allows users to limit to peer reviewed/scholarly articles from the result screen. It is said all journals indexed in the Web of Science, ScienceDirect are scholarly and peer-reviewed!
