I’ve been playing around today with the online book access I can get through ACM. You can get access to about 500 books from Safari and 400 from Books 24×7. Mind you, there are thousands of books on the main Safari site, and thousands more on the main Books 24×7 site. A regular Safari subscription is $20 per month, and Books 24×7 is about $450 per year, so both those options are a bit expensive. There are some useful titles among the limited library of books available through ACM, but not too many recent ones. For instance, there’s a good bit of stuff on .Net 1.1, but very little on .Net 2.0. I don’t think I could just stop buying computer books, based on the selection available through ACM, but there is some good reference stuff there. There’s also not much you can do in the way of printing from either service, within the ACM section. Still, I’m going to try to keep this stuff in mind before running out and buying any more computer books, and I’m going to try to remember to seach these services the next time I’m trying to solve a programming problem.
