Two volumes, published by CBS College publishing, aka Holt, Rinehart and Winston in 1982, both titled "UNIX Programmer's Manual". Volume 1 (ISBN 0-03-061742-1) was the man pages, and volume 2 (ISBN 0-03-061743-X) was the supplementary docs, starting with “7th Edition UNIX — Summary”, dated September 6, 1978. They have perforated, 3-hole punched pages, clearly intended to be torn out and put into a three-ring binder. I've skimmed through both of them, and I can't find any obvious typesetting errors. "Typesetting Mathematics" shows some quite complicated equations. And in the quick reference in volume 1, all the troff special characters seem right, even up to less common characters such as \(bs. Is there anything specific that I should look for? Scans available if they would help. Greg -- Sent from my desktop computer. Finger grog@lemis.com for PGP public key.
