The Astronomical Data Center (ADC) at the NASA Goddard Space Flight Center is a major archive and distribution center for computer-readable versions of astronomical catalogs and journal data tables. The ADC's archives contain more than 1600 catalogs and tables of astrometry, photometry, spectroscopy, radio, high energy, and other miscellaneous data for stellar and non-stellar objects. These data files are documented in a standardized manner, developed in cooperation with the Centre de Donnees astronomiques de Strasbourg (CDS). The ADC's data collection is available via anonymous FTP from node in the /pub/adc/archives directory. The holdings can also be accessed from the ADC's WWW site, This site permits users to search the text of the documentation files to locate catalogs and tables of interest or to browse the archives. Hypertext author and keyword indices, and other browsing tools have recently been developed as additional aids to navigating the ADC's large collection of data sets. The ADC is currently developing services to allow researchers to easily locate data fields of interest within files in its archives. The ADC has also prepared three volumes of CD-ROMs that contain several hundred of the largest and most requested catalogs in both ASCII and FITS table formats.
