but it looks like you've beaten me to it!

14 The C Programming Language

11 Structure and Interpretation of Computer Programs

8 Introduction to Algorithms

7 Compilers: Principles, Techniques and Tools

6 Programming Erlang

5 The Mythical Man-Month

5 The Pragmatic Programmer

5 Applied Cryptography

4 Beautiful Code

4 The Little Schemer

4 Programming Perl
