My first thought was "I wonder if the C programming language would be on that list" and sure enough... Worth noting that, although the book is 45+ years old, it's aged incredibly well (I know, there have been multiple "patches" applied since the first edition). But considering how books that came out 5 years ago are wildly outdated today, while this one is just as relevant as it was when it first came out is a huge achievement. Major props to Ritchie and Kernighan.
