The HHHH Computing Library

Over the years, we H's have managed to accumulate a substantial library of books on computing. Here is a list of them, in no particular order:

The reference work for the Clipper database compiler. About as exciting as it sounds.
Common Lisp, an Alternative Approach
A pretty good lisp book, that's cool enough to have been written using TeX.
Prolog, Programming for Artificial Intelligence
Covers a lot of interesting topics, but reads like a textbook.
The C++ Programming Language
Stroustrup's classic C++ reference. A must have for any nerd library.
The C programming Language
The classic Kernighan and Ritchie C reference. A must must have for any nerd library.
Computer Graphics, Principles and Practice
The classic Foley, vanDam computer graphics reference. Extremely dense reading, but terribly useful. A must have for nerds who like graphics.
Artificial Life
Another great Steven Levy book.
Tcl and the Tk Toolkit
John Ousterhout's attempt at a Tcl/Tk reference. It's really more like a primer, and has proved to be a very difficult book to actually use in any serious way. Ousterhout may be the cool dude who wrote Tcl/Tk, but that doesn't mean he knows how to write documentation. The only decently written part of this book is the part that details interfacing Tcl/Tk with C.
Graphics Gems II
Graphics Gems III
Like Foley vanDam, full of difficult to read but terribly interesting computer graphics algorithms.
The Standard C Library
Delightful little reference about the standard C library, complete with sample implementation.
