This is my latest bibliography of good, publically available X Window System
technical material.  There may be other good papers in unpublished conference
proceedings and tutorial notes, but these are difficult to find, so I am not
listing them here.  There's alot of other stuff out there, but I think these
are the best references.  If you know of any other good ones, please let me
know.

There are two journals dedicated to material on X.  As they should be pretty
well indexed, the bibliography will only include selected papers.  These
journals are *The X Journal* (1097 Eastbrook Rd., Martinsville, N.J. 08836;
phone +1-908-563-9033) and *The X Resource: A Practical Journal of the X Window
System* (O'Reilly & Associates, 103 Morris St., Sebastapol, CA 95472; phone
+1-707-829-0515).

The MIT X Consortium hold an annual conference including paper presentations.
The proceedings from the 6th conference (January, 1992) are included in Winter
issue of *The X Resource* (see above).  Papers from earlier conferences were
distributed to attendees only and not formally published.

Many people have been asking questions about the bibliography.  No, I'm not
distributing it in any other format.  If your printer can't handle the UNIX-
style underlining, run it through the UNIX col filter or the equivalent on your
system.  The sample code from most of the books listed here is available on-
line, usually by anonymous ftp to export.lcs.mit.edu, uunet.uu.net, or
gatekeeper.dec.com.  Yes, I do accept (and appreciate) review copies of
material.  Yes, you may put copies of this in your books (see the permission
notice below), but please let me know and include the date and contact info
from the header.  Approximately one a month, updates to this bibliography will
be distributed through the comp.windows.x USENET group, the xpert Internet
mailing list, and anonymous FTP:
    export.lcs.mit.edu:/contrib/Xbibliography and
    gatekeeper.dec.com:/pub/X11/contrib/Xbibliography
Due to popular demand, I am also preparing a PostScript version.  This is
available only by anonymous FTP:
    export.lcs.mit.edu:/contrib/Xbibliography.ps
    gatekeeper.dec.com:/pub/X11/contrib/Xbibliography.ps
Please do not ask for updates other than these.

Sorry, I am not able to distribute copies of the material mentioned here.  Your
librarian or bookstore should be able to help you.

     tutorial on programming with the X Toolkit and a formal specification

     ISBN 0-201-55792-4. A good tutorial on Motif programming. It doesn't
     include lots of toy examples like some of the other books, but there
     are good practical examples and the descriptions of the widget func-
     tionality (especially the constraint widgets) are excellent. The sec-
     tion on subclassing Motif (mostly XmPrimitive) widget classes is not
     real complete, but still is far better than those in other Motif
     books. There is an introductory section on UIL, which is easier to
     understand, though not as complete as the section in the Motif
     programmer's guide. This book does not contain a tutorial on the X
     Toolkit intrinsics, so you will probably want Asente & Swick's book
     for that.

     covered, usually with examples. Others dislike the sometimes shallow
     coverage of complex subjects. Also, some of the material is biased,
     e.g. the Motif book does not cover the user interface language because
     the author of the book did not agree with the philosophy of UIL. These
     books are quickly updated to cover new MIT releases and recent edi-
     tions are much improved over older ones.

     1988-1991.  Interoperability between multiple clients running simul-

     answer RTFM to X questions, the 'M' is usually the ICCCM. A copy of
     the latest ICCCM is in the  MIT X11R5 distribution

     Press, 1992.  ISBN 1-555558-088-2. The Xlib and X protocol bible by
     the authors of X11. The third edition is a superset of the MIT docu-
     mentation on X11R5 Xlib, X protocol, XLFD, ICCCM, BDF, and the com-
     pound text encoding. This is THE specification of the core of X and is
     required for all serious X programmers, though it may be rough going
     for those with little experience in interactive computer graphics. See
     also Asente & Swick's companion book on the X Toolkit.

     A review of Quarterdeck's Desqview/X and Cayman System's XGator.
     Desqview/X is a full X environment (server and libraries) for DOS.
     XGator allows Macintosh applications to display on X servers. They
     conclude that these are excellent products, though the initial ver-
     sions do have some quality and performance problems.

     is popular with Motif beginners, but it is based on X11R3 and Motif
     1.0, so is somewhat out-of-date. The Motif user interface language

     also weak: see the Asente & Swick book for better coverage there.
