Northwestern University Library (NUL) uses a Kirtas  automated book scanner and the services of external vendors to reformat brittle books, digitize special collections, and fulfill targeted patron digitization requests. Prior to 2007, however, the Library lacked a mechanism for making digital book facsimiles available online. In fall 2007, the Andrew W. Mellon Foundation awarded NUL a one-year grant to develop software to gather page scans, apply book structure, prepare OCR and JPEG2000 derivatives, generate technical and preservation metadata, submit these book objects to a Fedora repository, and present a public book viewer with both page turning and search capabilities.
The public book viewing site, Northwestern Books (books.northwestern.edu) , became available in beta preview on April 6, 2009. The software developed through the Mellon-funded Mounting Books project is now available as open source via SourceForge.net  (summer 2009).
