Photographs are unique touchstones to the past. For more than 50 years Sherman Library has collected photographs that document the Pacific Southwest history. The Library's collections include over 40,000 images from the nineteenth and twentieth centuries. Paul Wormser, Sherman Library Director, will talk about the Library's photograph collections and share some of these unique images. He will also demonstrate the use of the new Sherman Library Digital Catalog, which includes many of the library's most interesting images.
