CiteSeer: Scientific Literature Digital Library

CiteSeerX is a scientific literature digital library and search engine that focuses primarily on the literature in computer and information science. It provides improvements in functionality, usability, availability, cost, comprehensiveness, efficiency, and timeliness in the access of scholarly knowledge.

Rather than creating just another digital library, CiteSeerX attempts to provide resources such as algorithms, data, metadata, services, techniques, and software that can be used to promote other digital libraries.
