Above the Search box on the Library's home page, there is a link labeled "databases" that will take you to an alphabetized list of all the resource databases the library has access to.
Each item on the list contains a description of and a link to the database named in the list.
On the right side of the list you will find of the four most frequently used databases.
Often, these databases are enough to find the 3 to 5 peer-reviewed articles you "need" for a paper. That said, each database is organized a little differently and intended for a different research method or topic so take the time to check out the different databases.
