The ADS Article Service Data Holdings and Access Methods

The NASA Astrophysics Data System article service provides access to scanned images of journal articles published since 1975 on the World Wide Web. The journals currently on-line include the Astro-physical Journal Letters and recent years of the Astrophysical Journal. Work is underway to complete coverage of the Astrophysical Journal and to scan all the other major US astronomical journals. The documents may be accessed by either requesting an article by specifying the journal name, volume and page, by requesting a table of contents of a particular journal, or directly from the list of references generated by a query to the ADS abstract service. For each available article we provide the options of browsing the pages on-line, retrieving either a PostScript or a PCL document suitable for printing, requesting the document to be faxed anywhere in the US, or downloading the scanned images to a local computer.
