I read that in our paper on Sunday (I live in San Antonio). I was like, "Why do you need a brick-and-mortar library to check out e-books?" I check out e-books from the library all the time, and never leave the house.
I just don't really see a need for it, other than that part of town is severely underserved by city services and they see this as a relatively cheap way to put a library down there.
That said, my husband and I will make the trek to see it when it opens.
