The Waring Library Society (WLS) is a "friends of the library" group founded in 1979 to support the mission of the library, specifically developing the collections, raising funds for the Library's endowment, promoting membership and perpetuating interest in the history of the health sciences. WLS also serves as advocate for the Waring Library within the University and in the community at large.
The Society sponsors events, conservation, and student programs, as well as two lectures per year, the Warren A. Sawyer lecture held in the fall, and the Joseph I. Waring, Jr. lecture held at the Annual Meeting in the spring. These events are open to the public and feature speakers who are prominent in their fields. The Society also sponsors the Student Medical History Club. This student group meets monthly at noon for lunch and a brief informal talk on some aspect of medical history.
