Thanks, sourwolf, that's good to know and very much appreciated. I never would have thought about contacting the home-town library.
Due to your response, I looked up Mom's local library web site and sent them an e-mail asking about e-book availability.
Mom is not a buyer of books, she likes her library. But she has commented on how the large books are uncomfortable for her to hold anymore, so I thought a Nook would be a good gift.
