Well, it's a quandary. Publishers want to sell books. Academics and students want to use those books for free, and with a volume of use that would make ever purchasing the book unnecessary for all but a handful of them. I'm sure this will seem a reasonable position to some folks here, but I think it's clear which side is asking for the moon.
Incidentally, if you RTFA it's clear Georgia State was operating well beyond what might be considered "fair use" (which Georgia State more or less admitted by tightening its policies after the lawsuit was filed).
