The reason I went to 3 libraries? Paperback books often are not listed in the catalog. When checked out they come up adult paperback, so this makes it hard to know which library has what. Also I can not request a book if it isn't in the catalog. So I visit the libraries. Which I love to do. Being surrounded by that many books is a little slice of heaven. Just looking through stacks for something to grab your attention and then relishing in the joy of choosing stacks of books to bring home.
I also am a fan of the library because we have bookshelves, bookshelves, bookshelves overflowing at our house. Being able to send the books packing when we are done is truly the simple joy!
