I remember the TeXbook, from back when it came out (more or less). One of those books that tells you what's going on, provides a very good summary of its context, and makes you want to read it. More documentation back then seemed to be of higher caliber, than much if not most of what we wade through, today. I think the people writing it had more time and resources for attention to detail. And perhaps more need. There was no generally public Internet for updates and corrections including turning your product from a pain in the ass quasi-brick to something useful. You had to get it right, up front.
