This is a great, short video from RMIT University in Australia that explains what scholarly/peer-reviewed/articles and library databases are.
PittCat is the main searching tool for all of the materials owned by the University Library System (ULS), including articles, books, ebooks, journal articles, ejournals, audio and video, digital images, government documents, microfilm and movies.
Listed below are multidisciplinary databases, covering a wide range of topics, that you can used to get started. (JSTOR does not include magazines or newspapers.)
Printing articles on campus? See the student instructions under "Printing Services" near the bottom of the campus technology web page for instructions on using mobile print stations and locations for other printers on campus.
Sometimes you won't be able to get everything you need from a multidisciplinary database and need something more specific. Pitt offers many subject-specific databases that you can use. A few popular choices are listed below.
