Introduction

This file contains a reasonable technical bibliography on the X Window
System. It was compiled by Ken Lee and made available on newsnet. It is
provided "as-is" as a useful source for programmers and users of the
POPLOG/X interface.

----------------------------------------------------------------------------

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  There may be other good papers in unpublished conference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
decwrl.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.

Berlage, Thomas, OSF/Motif: Concepts and Programming, Addison-Wesley, 1991.
				 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.

O'Reilly and Associates, Definitive Guides to the X Window System, O'Reilly
				 and Associates, 1988-1992.  There are three main types of books in
				 this series: "programmers manuals" (tutorials for programmers),
				 "reference manuals" (man pages, similar to the MIT manuals) and "user
				 guides" (tutorials for non-programmers). The volumes in this series
				 are: Vol. 0:  X Protocol Reference Manual, Vol. 1:  Xlib Programming
				 Manual, Vol. 2:  Xlib Reference Manual, Vol. 3:  X Window System
				 User's Guide, Vol. 3M:  X Window System User's Guide (Motif Edition),
				 Vol. 4:  X Toolkit Intrinsics Programmers Manual, Vol. 4M:  X Toolkit
				 Intrinsics Programmers Manual (Motif Edition), Vol. 5:  X Toolkit In-
				 trinsics Reference Manual, Vol. 6:  Motif Programming Manual, Vol. 7:
				 XView Programming Manual, Vol. 7 Companion:  XView Reference Manual,
				 and Vol. R5 Update:  Programmer's Supplement for X11R5. Some people
				 like these because of their broad coverage; most interfaces are
				 covered, usually with examples. Others dislike them because coverage
				 of complex subjects is often superficial and inferior to that in com-
				 peting books. Also, some of the material is biased, for example the
				 Motif book does not cover the user interface language because the au-
				 thor of the book did not agree with the philosophy of UIL. The most
				 recent versions of these books are based on X11R4 or X11R5.
