Ingram Library subscribes to over 400 databases where you can find the following kinds of information:
GALILEO is the directory that lists these different resources. GALILEO itself is not a database, just a listing.
To see a listing of all of the databases, go here: http://www.galileo.usg.edu/scholar/westga/databases/all/
Since this list is a bit overwhelming, UWG Librarians have created research guides for all majors (and some for individual courses, like this one). You can find all of the guides here: http://libguides.westga.edu/index.php
Academic Search Complete is a multidisciplinary database which means it has popular and introductory scholarly information for nearly all fields of study. It's the one we recommend you start with, especially for most of your first year courses. In Academic Search Complete you can limit to scholarly publications and email yourself the fulltext of many articles (not all are available fulltext in Academic Search Complete).
