If you are an IT/IT related student then student membership of the ACM is a pretty good deal. For USD$19 you get access to:
- 500 online books from Books24x7 (can't download but cheaper than buying)
- 3,000 courses from SkillSoft
- online magazines
- MS software (might be be the same as Dreamspark - I'm not a student so can't test)
I joined as a graduate student when there was a lot less on offer and it was good value then but it is even better now for students. Once you have graduated it is a lot more expensive <sigh>
Not that I'm eligible for this now, but would be even better if their digital library was included in the package for $19! ;)
