What are some good books about books/reading?

Some of my favorite novels are about books, reading, or authors. I have been trying to find some other books I might enjoy. So far my favorites have been 'Shadow of the Wind'- Carlos Ruiz Zafon, 'The Book Thief'-Markus Zusak, and 'The Thirteenth Tale' by Diane Setterfield. Any suggestions would be appreciated. Thanks so much!
