Funding for the development of the Alexandria Digital Library middleware and the ADEPT Virtual Learning Environment, under the NSF DLI2 initiative, has now ended. Future support for enhancement and dissemination of the operational library infrastructure will be provided by the Davidson Library UCSB. ADL technology will be the starting point for designing a distributed geospatial library network funded by the Library of Congress Digital Preservation Initiative. Please see for more information.

The educational evaluation component of the DLI2 project continued into 2005, and further work on the ADEPT software and its broader deployment are under way via a joint U.S. (NSF) and U.K. (JISC) funded project: DialogPlus - Digital Libraries in Support of Innovative Approaches to Learning and Teaching in Geography.

   Alexandria Digital Library

The project began in 1994 with the development of the Alexandria Digital Library (ADL), a distributed digital library with collections of georeferenced materials and services for accessing those collections. Distributed means the library's components may be spread across the Internet. Georeferenced means the library's holdings are associated with a region (footprint) on the surface of the Earth. Phase I of the Alexandria Digital Library Project was supported by the NSF's Digital Library Initiative: NSF IR94-11330.

Alexandria Digital Earth Prototype

The Alexandria Digital Earth Prototype (ADEPT) is the second stage of the Alexandria Digital Library Project. Funded by the National Science Foundation (ISI-98-17432), ADEPT's goal is to integrate the success of the first stage of ADL into the classroom by creating a Digital Learning Environment for educators and students based upon ADL technology.

The Alexandria Digital Library Project is headquartered on the campus of the University of California at Santa Barbara. The Alexandria Digital Library is hosted by the Davidson Library.
