Books about Books

This is a translation from my original post over at the Cave.

After reading Ivanius' beautiful article about Ivanius about libraries, I went on a small recursive loop that resulted in a short list of books where books are main characters or motors of the story.

• The Name of the Rose
  By Umberto Eco: During the XIV century, an eery benedictine monastery is silent witness to a rash of murders related to a misterious book hidden within its library.
  
  
  
• The Dumas Club
  By Arturo Pérez-Reverte: An antique book hunter gets into grave trouble while researching an original manuscript of The Three Musketeers and an ancient book supposedly written by devil worshippers.
  
  
  
• The Neverending Story
  By Michael Ende: An introverted boy finds a book called the Neverending Story; reading it, he finds himself one of the characters involved in the rescue of Fantasia from the Nothing.
  
• The Necronomicon and other stories
  This "terrible and forbidden" book comes from the imagination of HP Lovecraft and is a main character in many of his horror stories.
  
• The Myst novels: The Book of Atrus, The Book of D'ni and the Book of Ti'ana
  By Robyn and Rand Miller in collaboration with David Wingrove: Prequels to the videogame where the books literally transport the reader to different worlds with subtly different natural laws
  
  
• The Spiderwick Chronicles
  The first one of this series of books tells the tale of two children who move to a weird country house, where they find a field guide about the supernatural beings that inhabit the region.
  

Dear reader, if you think of another title, please add it to the list. I am not including anthologies nor textbooks nor reference works, although I was tempted to include Adler's and Van Doren's famous "How to read a book" for purely sentimental reasons.
