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.

Digital Earth

The objective of ADEPT Digital Earth (DE) development is to design, implement, and evaluate real-time 3D interfaces for visualizing ADEPT geospatial digital library technology. Research includes:

  • applying existing DE and related technologies to known problem areas
  • expanding the potential user base of DE and geospatial digital library technology
  • creating customer feedback loops to drive further research and development in this area
