Alexandria Digital Library Project

Project Description
The Alexandria Digital Library (ADL) is a distributed digital library with collections of georeferenced materials. ADL includes the operational library, with various nodes and collections, and the research program through which digital library architectures, gazetteer applications, educational applications, and software components are modeled, prototyped, and evaluated.

ADL provides HTML clients to access its collections and gazetteer, and provides specific information management tools, such as the Feature Type Thesaurus for classing types of geographic features, as well as downloadable software code.
