The NASA technical reports server is an experimental service that allows users to search the many different abstracts and technical report servers maintained by various NASA centers and programs. Specifically, it is a unified interface to many separate WAIS servers. NTRS is both a superset of the various servers, and a canonical listing of the servers.
