Bancroft_Library

The Bancroft Library is the primary special-collections library of the University of California, Berkeley. It was acquired from its founder, Hubert Howe Bancroft, in 1905, with the proviso that it retain the name Bancroft Library in perpetuity. The collection at that time consisted of 50,000 volumes of materials on the history of California and western North America. It is now the largest such collection in the world. The library's current building, the Doe Annex, is in the center of the university's main campus, and was completed in 1950.
