The library has over 200 databases, many of which will provide you with scholarly journal articles. Best to start there; use the subject pull down bar to select your topic's subject, then use the type pull-down bar to select scholarly journal articles. This'll allow you to choose the best database for your needs. Listed below are just a very few of our databases.
After you've run your search, most databases will offer a academic journal or scholarly (peer-reviewed) limiter off to the left.
To find trade publications in library databases, run your search first. Off to the left, under the Source Type limit, note there is a trade publications limiter.
Find magazines in Readers' Guide or Readers' Guide Retro.
