Comprising 22 libraries, the UC Berkeley Library has one of the world’s most comprehensive academic research collections, from the trove of primary documents chronicling the West at Bancroft Library, to the collaborative and innovative spaces at the Moffitt Library, to the vast and unparalleled collections at Doe Library — a beacon of information standing in the shadow of the iconic Campanile. Together, these libraries help sustain UC Berkeley as a leading producer of knowledge. The Library holds more than 13 million volumes in its world-renowned collections. Materials include paintings, lithographs, papyri, audio and video recordings, and ephemera such as leaflets from the Free Speech Movement, a note from Helen Keller to Mark Twain in honor of his 70th birthday, and vintage costumes worn by Berkeley’s beloved mascot, Oski. The Center for Connected Learning, a "collider space" where students will have access to one-stop consultation on retrieval, evaluation, and use of advanced information resources and will acquire skills required for 21st century information literacy will soon be open in Moffitt Library.
