I don’t have any idea what CERM stands for. Keeping “CERM for a reference text” is probably a good idea. But then, I’m an old guy and grew up using books to learn things, and I’m a lover of good tech books, good engineering ref. books. What did you pay for it, was it helpful in the intended endeavor, did you get most of your moneys worth once already? What would you get for it if you sold it used, and there is probably a new Ed. already, to boot? If it’s clear and simple and straight to the point, without a lot of theory, so be it, it will still jog your memory and help you approach some of your problems, and you know your way around in it. What will it be worth if it helps you solve an important problem now, or makes you think enough to look more deeply for the needed detail. I’d keep it. There have been damn few engineering texts and ref. books that I’ve sold, used, over the years, and I’d bet I’ve used them all at one time or another, some much more than others, of course.
