Just like C, there is a stark beauty to the original K&R C Programming Language book. And there's an admirable clarity in the writing that has set the standard for all language manuals that have followed. It is, indeed, a terrific read. As long as you're not trying to learn C.

It's really out of date. It doesn't cover subsequent C standards; and it doesn't cover any of the best practices that have subsequently evolved to protect us from the things in C that are deeply awful (in retrospect) in the original. Or any of the evolved practical lore for writing good, portable, safe C code.
