While it seems like programming books are sold by weight, these days, it makes a certain amount of sense for a book like this (or Steven's _Advanced Programming in the Unix Environment_) - it's a detailed reference for Unix's rather large API. It'd probably be better in multiple volumes, though. There are some good, short programming books. (Many of them were co-written by Brian Kernighan.)
