The University of Michigan Digital Library Project

Other NSF/DARPA/NASA Sponsored Digital Library Web Sites

The University of Michigan Digital Library Project (NSF-UMDL) is a multidisciplinary collaboration among faculty and staff throughout the University of Michigan. Initial use and evaluation of the NSF-UMDL will take place in science classes in Ann Arbor, Michigan high schools and the Stuyvesant High School in New York City, as well as instruction and research at the University. Access will also be available through Ann Arbor and New York City public libraries. External partners to the project include: IBM, Elsevier Science, Apple Computer, Bellcore, UMI International, McGraw-Hill, Encyclopaedia Britannica Educational Corporation, and Kodak.

The content will emphasize a diverse collection, focused on earth and space sciences, which can satisfy the needs of many different types of users. The content will be supplied by publishers, although the project will eventually allow all users to publish their work. A related project, the Journal Storage Project (JSTOR), will digitize and make available all issues from the first publication through 1990 of ten economics journals to the NSF-UMDL.
