The Bancroft Library in the center of the Berkeley campus of the University of California, Berkeley, is the university's primary special-collections library. 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 the North American West. It is the largest such collection in the world.
The inception of the Bancroft Library dates back to 1859. William H. Knight, who was then in Bancroft's service as editor of statistical works relative to the Pacific coast, was requested to clear the shelves around Bancroft's desk to receive every book in the store having reference to this country. Looking through his stock he was agreeably surprised to find some 50 or 75 volumes. There was no fixed purpose at this time to collect a library. Noticing accidentally some old pamphlets in an antiquarian book-store, he thought to add these to his nucleus; then looked more attentively through other stores and stalls in San Francisco, Sacramento, Portland and Victoria, purchasing a copy of every book relating to his great and growing subject. During his next visit to the eastern states, without special pains or search, he secured whatever fell under his observation in second-hand stores of New York, Boston and Philadelphia.
He had collected in all not far from a 1,000 volumes and had begun to feel satisfied. "When, however, (he declares) I visited London and Paris, and rummaged the enormous stocks of second-hand books in the hundreds of stores of that class, my eyes began to open. ... And so it was, when the collection had reached one thousand volumes, I fancied I had them all; when it had grown to 5,000, I saw it was but begun." (177) Finally, special journeys were made to all parts of Europe, as well as the Americas, in the interest of his collection. "And not only was every nook and corner of the world thus ramsacked, but whole libraries were purchased as opportunity offered." While his vague ideas of materials for writing a history gradually assumed more definite form, Bancroft had as yet no idea of writing a history himself. As the collecting proceeded his subject enlarged, until the territory covered was the entire western part of North America from Panama to Alaska, including the Rocky Mountain region, all Central America and Mexico, or about one-twelfth of the earth's entire surface.
