I use the library regularly. I used to collect lots of books and finally decided that the library takes such good care of "my" collection that I would just pretty much leave it up to them. We have an author's club you can join and select the authors that you like. When that author comes out with a new book you are automatically on the list to be notified when it is being held for you.
Also, here in Missouri, if you want a book that is not available in your county's system, the local library will borrow it from another site somewhere in the state and notify you when it is available for pick up at your local branch. I have even requested books that were nowhere in the state and they purchased a copy for me to borrow. I love our library.
