Facing Memorial Glade in the middle of the Berkeley campus, Doe Library is the main library of the UC Berkeley system and one of the campus's grandest buildings.
Open to visitors
The UC Berkeley Library says Doe is open to all researchers and visitors, with no identification, registration, pass or prior arrangements required. Some services, collections and rooms are limited to UC Berkeley students, faculty and staff. The library's listed hours are 8 a.m. to 9 p.m. Monday through Friday and 1 to 9 p.m. Sunday, and it is closed Saturday. Hours change over breaks, so check the library's calendar. The building is wheelchair accessible. The underground Main Stacks require a Cal ID.
History
Wikipedia says the library is named for Charles Franklin Doe, who left money for its construction in 1904. Émile Bénard won a 1900 design competition, and the Neoclassical building was completed in 1911. It connects to the Bancroft Library.
The stacks underground
According to Wikipedia, the Gardner (Main) Stacks, built in 1994, are a four-story underground structure under Doe's entrance plaza and part of Memorial Glade, lit by four large skylights. They hold about 2.3 million volumes on 52 miles of shelving, mostly in the arts, humanities and social sciences. An underground hallway links them to Moffitt Library. With the main collection underground, visitors now come to the Doe building mostly for its large reading rooms and reference collections.
Mark Twain
Wikipedia says the library holds the Mark Twain Papers, a large collection of Samuel Clemens' manuscripts, letters and other materials. A statue of Twain holding Adventures of Huckleberry Finn, by Gary Lee Price, stands at the entrance. Wikipedia notes that people often mistake it for Albert Einstein. Nearby is the Phoebe A. Hearst Museum of Anthropology.
