Classic Academic Textbooks

Question

I'm familiar with both the Wizard Book:

Structure and Interpretation of Computer Programs

and the Dragon Book:

Compilers: Principles Techniques and Tools

However, I'm curious to find out which other classic academic textbooks people would consider essential reading for a programmer.

Answer 1

If the word is "classic", then I'd say the collection from Knuth's "The Art of Computer Programming".

Answer 2

Introduction to Automata Theory, Languages, and Computation

Also see:

A must have 'Design Patterns: Elements of Reusable Object-Oriented Software'

Answer 4

I would say the following is a classic!!

Brian Kernighan book on C Language
