The Red Book Of Westmarch

So you're saying that the three volumes are other things bilbo wrote?

In the next day or two Frodo went through his papers and his writings with Sam, and he hadned over his keys. THere was a big book with a plain red leather covers; its tall pages were now almost filled. At the beginning there were many leaves covered with Bilbo's thin wandering hand; but most of it was written in Frodo's firm flowing script. It was divided into chapters, but Chapter 80 was unfinished, and after that were some blank leaves. The title page had many titles on it, crossed out one after another, so:

My Diary. My Unexpected Journey. There and Back Again. And What Happened After.
Adventures of Finve Hobbits. The Tale of the Great Ring, compiled by Bilbo Baggins from his own obswervations and the accounts of his friends What we did in the War of the Ring.

I'm wondering if that's saying that the three other volumes are My Unexpected Journey. There and Back Again. And What Happened After.
Adventures of Finve Hobbits. The Tale of the Great Ring, compiled by Bilbo Baggins from his own obswervations and the accounts of his friends What we did in the War of the Ring. And that the diary is something different. And that Frodo just took that and him and sam added to that.

Argh, so confused.
