RefWorks is a web-based program that allows you to create your own personal citation database.  By installing a small program it can also help you add citations to your manuscript and format those citations in a number of different output styles.  The citation database that you build can be easily shared with colleagues here at Penn as well as those around the world.

[The Atwood library is in the restricted-access Hill Building. Visitors who do not have a Penn ID card that has been activated for the Hill Building can enter through the Ryan Hospital entrance at 3900 Spruce Street after presenting a current, valid photo ID. Alternatively, on-site access may be requested via the intercom at the University Avenue entrance by displaying a photo ID to the camera.]
