"The Art of Computer Programming, Volumes I-IV" by Donald E. Knuth (1968, 1969, 1973, 2011)
Originally planned as a single twelve-chapter volume, The Art of Computer Programming (or TAOCP, as it's often known) is a four-volumes-and-counting set that’s regarded as the industry's defining work. Bill Gates once said, "If you think you're a really good programmer ... read (Knuth's) Art of Computer Programming.... You should definitely send me a résumé if you can read the whole thing."
