This book covers Tcl/Tk 8.0 (script and C APIs), Expect, incr Tcl, incr Tk, Tix, TclX, BLT, Oratcl, Sybtcl, and Tclodbc. It also has a 12 page chapter called "Hints and Tips for the Tcl Programmer".
It is one of the the few books currently at O'Reilly's with Tcl in the title. The wonderful Expect book also of course deals extensively with Tcl, as well as the Expect extension.
Let's not forget the Tcl/Tk Pocket Reference
George Howlett writes, "It's a great reference book. How great? Not only did the authors laborously go through the BLT manual pages, but compared the source code too. You're right, there's no manual entry [for blt::winop, for example], but they documented it from the sources." (!)
