Out of print

I really wanted to assign Sheri S. Tepper's brilliant novel Grass for my science fiction course next semester, but apparently it's out of print. That's frustrating. Especially in the era of the 'Net, shouldn't someone figure out how to make all of those out-of-print books available to potential readers in something other than a virtually unreadable text-only format?

Hmm. I think there's a niche there.
