Knuth’s work is best read on paper. You can buy the Art of Computer Programming, Volume 4, Fascicle 6: Satisfiability directly from Amazon or the publisher.

Knuth has stated that he hopes to eventually cover: the art of computer programming volume 6 pdf
However, there is a catch. Knuth famously rewrote the foundational architecture of the series. Volumes 1-3 use a hypothetical assembly language called MIX. Volumes 4 and beyond use a modernized version called . Because Knuth is a perfectionist, he decided that Volume 6 could not be published until the MMIX computer architecture was fully stable and documented.
