ADS
The Astrophysics Data System (ADS) is a NASA-funded project which maintains three bibliographic databases containing more than 5.3 million records: Astronomy and Astrophysics, Physics, and arXiv e-prints. The main body of data in the ADS consists of bibliographic records, which are searchable through our Abstract Service query forms, and full-text scans of much of the astronomical literature which can be browsed though our Browse interface. Integrated in its databases, the ADS provides access and pointers to a wealth of external resources, including electronic articles, data catalogs and archives. We currently have links to over 5.5 million records maintained by our collaborators.

HEASARC
The High Energy Astrophysics Science Archive Research Center (HEASARC) is the primary archive for high-energy astronomy missions, in the extreme ultraviolet, X-ray and gamma-ray wavelengths. The HEASARC provides archival data, multi-mission software and analysis tools, and information about current and past observatory missions. The HEA Division is a partner in the HEASARC with NASA's GSFC.
