I'm a big library user. I'm blessed to live where we have excellent public libraries organized in a county-wide system; I can borrow from and return materials to any of the 28 branches. And I can ask for anything circulating from any branch to be delivered to me at whichever branch is most convenient for me. They'll even get books not in the county to me from elsewhere in the state. (I've done that three times and it still amazes me.)
My most recent special orders were for books by gay athletes; baseballer Billy Bean and basketballer John Amaechi. I recently ordered the first book in Anne Zouroudi's Seven Deadly Sins mystery series and the only one of Susan Conant's Dog Lovers Mysteries that I haven't yet read.
It's like I've been on a buying spree and I don't pay a cent. As long as I renew the books and return them in time...free and easy.
