Scientists have been using bibliographic databases as an aid to search for and retrieve scholarly papers for several decades. Increasingly, these systems have evolved into modern digital library environments which make them more accessible, personal, and integrated with other scholarly archives. I will discuss some of the technologies that the NASA Astrophysics Data System project is considering using in order to improve its role as the central digital library for Astronomy.
Among them: exploiting properties of bibliographic records as well as relationships between them to enable discovery; use of knowledgebases to implement semantically enhanced searches; adoption of resource URIs to express relationships between bibliographic metadata and related resources. This talk will be designed to elicit feedback from the communities of developers and scientists.
