You may use these encyclopedias to find background information, dates, and possible other sources, but you cannot cite these in your paper.

In some of our databases in Engineering and other areas, the database does not allow you to check that you are shown only peer-reviewed journal articles. To find out if a journal is refereed (also called peer-reviewed) you have two options:

1. Go to the journal publisher's web site to read the Advice to Authors and the About this journal. These are the most likely places that state if articles are sent out for peer-review.

2. Check Ulrichsweb (see below) to see if there is a little referee shirt icon in the left hand column.  Search by journal name.

If you need more help discovering the peer-reviewed status, please contact Jenny or Ed. 

Remember, only your professor can tell you if an article is acceptable for your assignment.
