The only computer science book worth reading twice?

The book 'Structure and Interpretation of Computer Programs' by Hal Abelson and Jerry Sussman is considered a seminal work in computer science. It introduces fundamental programming concepts and explores a wide range of topics like higher-order computation, data structures, modularity, and language design using Scheme. The book emphasizes a stratified design approach, where each layer of abstraction builds on previous ones. It has influenced many and remains relevant 22 years after its first encounter by the author.
