Until 2008, the Library of Congress offered a "digital interlibrary loan" service, where materials too fragile to circulate were scanned and delivered via the Web.  It looks as though the program's funding was cut, so you can't browse a full title list, but they still provide a selection of fragile items which are in the public domain, including one of the oldest examples of bike porn.
