The Astrophysics Data System has extended its bibliographics service, the Astrophysics Science Information and Abstract Service (ASIAS) to include bitmaps of full articles from the Astronomical Journal, the Astrophysical Journal and the Astrophysical Journal Letters. Once permissions are arranged, we plan to provide bitmaps from 1975 to near real time for the ApJL. For the AJ and ApJ we plan to provide bitmaps from 1975 to either one or two years after publication.
We currently have 3 versions of the bitmaps:
\begin{enumerate} \item A GIF version with 75 dpi resolution for viewing on a computer screen. These bitmaps can be transferred and displayed quickly and are readable on a screen. However, they are not well suited for printing.
\item A PostScript version with 150 dpi resolution. This version can be printed quickly, typically a few minutes for a Letter, and is of sufficient quality for most purposes.
\item A TIFF-G4 compressed version with 600 dpi resolution. These bitmaps have the full resolution of the scanner and can be used to print plots and plates. They are large, take long to transfer and will not print on all printers. We will have some conversion software for printing these files on PostScript Level 2 compatible printers. \end{enumerate}
The bitmaps are accessible from the ASIAS through hyperlinks in the corresponding abstracts. They are also available directly through a WWW interface. The ASIAS is accessible at: http://adsabs.harvard.edu/abstract\_service.html
