LibraryU is an adult program series of the Bainbridge Public Library. Run entirely by volunteers, LibraryU sponsors programs such as Great Decisions at the Library, an eight-part foreign affairs discussion series; hosts Humanities Washington speakers; and presents other educational and cultural programs at the Bainbridge Public Library.

All Library U programs are free. Library U is sponsored by the Bainbridge Public Library with funding support from the Bainbridge Island Friends of the Library and a generous donation in memory of Louise Brody Weissman.
