I think you can also get access to the ACM library via membership. When I was in college I paid for a student membership, I think its was $25/year or something generally reasonable. Probably a better value proposition than my actual CS degree, not that its a great point for comparison.
That's true. Many of these sorts of memberships are at least a few hundred dollars when you are no longer a student, so they add up pretty quickly (but maybe have tax credits).
