Mardigian Search allows you to search through the entire library catalog and many of the library databases all at once, so it is a great place to start your search.
You can find Mardigian Search on the homepage of the library website.

Not seeing the article you're looking for? Too many or too few results? Try using Journal Search next. Instructions for using journal search can be found on the Find Specific Publications page of this guide.
