One way you can find out whether a journal is refereed / peer reviewed using the database Ulrich's Web. That link directs you to a url with our proxy, which will prompt you to log in for access.
Once in the database, search for the journal title. Journals that are refereed or peer reviewed have a black and white striped "referee shirt" icon next to their name in your list of search results.
