The Libraries' electronic books are listed in the catalog and in JSTOR, Project MUSE, and EBSCO eBook databases.
For journal articles, find a specific database in the Databases Directory on the main web page (Academic Search Complete and SOCIndex are two good ones for this area), or use FindIt and set limits (periodicals, online resources (for electronic material), or explore Serials for print and microform journals).
Ask an instructor or a librarian for help.
