Overview

This is a collaborative project between Old Dominion University, American Physical Society and Los Alamos National Laboratory. This project is building an Open Archives Initiative compliant federated digital library with an emphasis on physics for the The National Science Digital Library. NSDL is the comprehensive source for science, technology, engineering and mathematics education, it is funded by the National Science Foundation. This physics digital library will federate holdings from the physics e-print server arXiv, Physical Review D from the American Physical Society. We are also working with CERN to federate their collection. Other holdings are being imported from the Arc project. To federate collections with varying degrees of richness of metadata elements poses a number of challenging questions, which we are addressing, in the areas of resource discovery, creation and maintenance of harvested metadata, and economic sustainability. We are supporting high-level services such as cross-reference linking, which is based on OpenURL and leverages the Citebase research at Southampton.
