The Red Book of Westmarch

The Red Book of Westmarch is a fictional manuscript in J.R.R. Tolkien's works, serving as the in-universe source of the stories about Middle-earth. It is depicted as a book written by hobbits, including Bilbo and Frodo Baggins, containing their accounts of adventures such as "The Hobbit" and "The Lord of the Rings." In reality, Tolkien used the Red Book as a narrative device to lend authenticity and historical depth to his stories, framing them as ancient histories recorded by hobbits from their perspective.
