Scholarly Sources Online by Subject
The following resources can be used to search for scholarly information, especially journal articles. Many of the subscription-based databases that academic and public libraries subscribe to, such as JSTOR, also have free public versions available. These free versions often do not contain the same full-text content found in the paid versions; however, they can be used to locate citations. Public libraries with interlibrary loan services can often fill requests for materials located through these resources.
