The following information is quite old - it comes from a FAQ turned over to another community member, was updated once or twice, and then never again. URLs may frequently be stale. However, journal references should be accurate and provide a historical basis for Tcl publication. If you are someone who wants to contribute to the Tcl community, feel free to update the following as you find newer information.
Information about inaccuracies in the bibliography is also welcome.

s. "Tcl and Concurrent Object-Oriented Flight Software: Tcl on Mars", by David E. Smyth, Mars Pathfinder Flight Software Team, Jet Propulsion Laboratory.
Describes the use of Tcl on the "Mars Pathfinder" project, in which Tcl (with several extensions) is used in several ways: as the language for inter-object messages within the object-oriented flight software; as the implementation language for the monitor and control environment; and as the initial implementation language for some of the flight software itself.
t. "Ariadne", by Thomas A. Phelps, University of California, Berkeley.
This paper provides a brief description of a core platform of services for the construction of interactive multimedia document manipulation tools (browsers, editors, and so forth).

D. Published articles, books, and similarly available resources
1. Computer Shopper, V12 N12, page 862 had an article referencing Tickle, the shareware package under Macintosh System 7 which is based on Tcl.
2. MacWEEK, Sept 14, 1992, V6 N32, page 91(1), Enhancing text editors for Mac developers. This article is a product announcement for Alpha 5.0, the Macintosh editor which incorporates Tcl.
3. Computer Language, V9 N7, page 76 had an article referencing Tcl in a hardware/software testing package which talks to a remote machine via a proprietary interface card.
4. SunWorld, V5 N10, pages 95-96 had a article discussing Tcl, Tk and expect.
5. UNIX REVIEW, V11 N4, April 1993, pages 93-94, Tcl, Tk, and friends by Richard Morin. The article, a part of "The Internet Notebook", mentions a little about Tcl and Tk, where to find the sources, where to find the draft of the book, and where to find the contributed software.
6. SunExpert, V4 N3, pages 32-36, by Richard Morin. As part of Morin's I/Opener series of articles, this is just a brief overview of Tcl and Tk. It mentions some of the technical ideas behind Tcl and Tk, where to find the Tcl source and mentions that the draft of the book is available for ftp. A 'hello, world' 3 line wish script is really all that is shown.
7. Libes, Don, "Obfuscated C and Other Mysteries", Wiley & Sons, January 1993.
This book has a whole chapter on Tcl. Aimed at the C programmer, it describes how to effectively use Tcl from C applications. Another chapter is on Expect - a walk-through of some of the more interesting code in Expect. These chapters originally appeared as separate articles in The C Users Journal, Vol. 8, No. 7, July 1990, and Vol. 9, No. 1, 1991. (Incidentally, the reason the book has such a peculiar title is that it also contains explanations of the Obfuscated C Code Contest winners.)
8. IEEE Design & Test of Computers, June 1993, pages 46-54, "RISE++: A Symbolic Environment for Scan-Based Testing" by Steve Vinoski. An article describing a system called the Remote Interactive Scan Environment (RISE++) that marries Tcl with RPC for the purpose of testing remote computer systems.

10. Proceedings 1993 Tcl/Tk Workshop, Berkeley, CA, June, 1993. See above for online version information concerning these proceedings.
11. iX (multiuser/multitasking magazine), September 1993, pages 76-84 and 182-185. Two articles written in the German language. These concern the design (interpreter and library) of Tcl/Tk and its connections with C++. The articles say where to find the packages and some associated tools (such as XF). There are short examples on how to write programs with Tcl/Tk (taken from the demo-directory of the package) and examples on using XF. Very informative.
12. Network Computing (CMP Publishing, Inc), November 15, 1993, pp. 99 "Very Rich E-Mail". References safe-tcl.
13. The Addison-Wesley Publishing Company's quarterly newsletter "Innovations" dated Winter 93/94 contains an interview with John K. Ousterhout on pp 2,9,10. It mentions the April 1994 release date, Dr. Ousterhout's background at UCB and involvement in Sprite. John gives a overview of what Tk and Tcl are, what companies are using Tcl, where Tcl/Tk fits in relationship to AWK, Perl, Motif, and X Windows (sic), mentions there are between 10,000 and 50,000 people developing applications in Tcl/Tk, discusses where in the classroom the textbook fits, and gives an overview of John's view of the future of Tcl/Tk.
Also on page 3 of the same newsletter is the overview of the book listing it as 512 pages and a list price of $36.75.
One can send email to [email protected] (Pradeepa Siva) to request a copy of the newsletter, or call him at Addison-Wesley Publishing Company 617/944-3700, ext 2940, or call Addison-Wesley directly to request it at 800/238-9682.

15. UNIX Review, March 1994, V12 N3, p87-90. Tickled Pink, by Kevin Richard and Eric F. Johnson. This is part of the programming column "CROSS THOUGHTS".
The authors attempt to provide a very brief taste for Tcl/Tk and to convey the purposes for which they consider Tcl suited. They provide a standard example of "Hello, world" in Tcl, and also a version written in Motif/C.
There were quite a few surprisingly negative remarks in a column which tried to be positive about Tcl/Tk.
16. iX, January 1994, pp 148-152, another German article about the interpretative class system that is a part of the GOOD graphics system.
17. John Ousterhout has written the book _Tcl and the Tk Toolkit_. It is published by Addison Wesley.

This article discussions the Motorola PowerPC simulator applications which were developed to permit early development and testing of PowerPC-based software such as compilers. The simulators are Tcl applications and the article discusses several benefits of using Tcl as a command language. Anderson also mentions plans for the next generation of simulators to have user-extendable GUIs based on Tk.
27. Tcl 7.3 is a part of the X11 R6 contrib distribution. So it will probably appear in any publically distributable forum in which entire package appears. Tk 3.6 is not, from my understanding, a part of the contrib tapes, etc.
28. The X Journal, volume 3, issue 1 (September-October 1994), pages 74-83: "X for the new user", by Jerry Smith. Contains a brief mention of Tk as an alternate user interface technology, and a reference to the Hypertools article by Ousterhout and Rowe.

31. Don Libes has written the book _Exploring Expect: A Tcl-Based Toolkit for Automating Interactive Applications_. It is published by O'Reilly and Associates.
From the announcement:
"For all of you who thought that the Expect man page was too long and too terse at the same time, this book provides relief. _Exploring Expect_ is an introduction and comprehensive tutorial to Expect. Numerous examples are provided and explained, demonstrating how to save you time and money. Example topics include how to write patterns, do signal handling, use Expect as a telnetable daemon, and use Expect with Tk and other Tcl extensions.
"The book also includes an innovative introduction to Tcl - if you've had trouble using Tcl before, all of a sudden, it will make a lot more sense. And while Exploring Expect concentrates primarily on using Expect with Tcl, programmers attempting to automate interactive programs using C, Perl, Python, or any other language will find this book helpful because many of the concepts underlying Expect-like programming are common to all languages."
