Appendix G. Sources of Additional Information

This appendix describes where you can get more information about Xlib and about X in general, including other books on the subject and the various ways to get the source code for X.

This appendix lists a few of the official and unofficial sources for information about the X Window System and associated software.

Note that some of this detailed information may become dated rather quickly. The best source of current information is the comp.windows.x network news group, described later in this appendix.

You can get the X software directly from MIT on three 9-track 1600-BPI magtapes written in UNIX tar format or on one 9-track 6250-BPI magtape, along with printed copies of MIT’s manuals, by sending a check in U.S. currency for U.S. $400 to:
