Agree on the edit. For clarity: about 700 Safari online books, videos from O'Reilly and other publishers are available to ACM Professional Members without a subscription to the Digital Library necessary. In addition 500 Books24x7 titles and more than 150 Morgan Kaufmann and Syngress books are available to ACM Professional and Student members, again without Digital Library subscription required. Professional membership to ACM is about $100, and subscription to the ACM Digital Library is an additional $100. Student memberships fees are reduced to 20-30% of that.
