A Word Related to Books that begins with the letter R

Question

I'm currently coding items for my game and I thought of a really funny one, but I'm having trouble figuring out what the final word should be. Here's what I'm thinking:

The item goes in the trinket slot of the character page, and it looks like a book. I wanted to have each word of the book name spell out "Too Long Didn't Read". Here's what I came up with off the top of my head:

"Tildra's Lost Dragon ______"

I was thinking the last word should be related to a Tome, Bestiary, or Manuscript; but I'm at a loss for words that start with 'R' that could finish this item name. Are there any words at all that could fill the blank? Even an archaic one?
