The Marjorie G. and Carl W. Stern Book Arts & Special Collections Center at the San Francisco Public Library holds a variety of collections relevant to San Francisco history, as well as printing history, calligraphy and lettering, humor, little magazines and zines, and early children's books. Much of this material is available from the website in digital form, along with instructions on how to use print-only resources in person. There are a couple of ways to easily approach the digital material. Book Arts & Special Collections celebrated its 50th anniversary recently, and an essay on collection strengths prepared for that celebration can still be found on the website. There are also persistent links to collection highlights in a left sidebar on all the pages, such as the Robert Grabhorn Collection on the History of Printing and the Development of the Book. As one would expect from a special collection in San Francisco, the Book Arts & Special Collections Center makes use of new technology. Visitors will find a selection of short videos on letterpress printing on YouTube, linked to from the Grabhorn Collection. There are also e-books from the George M. Fox Collection of Early Children's Books, available as high resolution digital books in the Internet Archive.
