The Other Scrolls

The Other Scrolls were a collection of Gallifreyan prophecies bound in reptile skin.

Willhuff found a copy in the Librarinth and gave it to the Infinity Doctor. He burned it because he did not want to know the future, preserving his free will. (PROSE: The Infinity Doctors)

In one timeline of the War in Heaven, the book was held in high security on Gallifrey. (PROSE: The Ancestor Cell)

Behind the scenes
The Other Scrolls, identified by their reptile skin binding, appear in Lance Parkin's Fishy Business as the one book that Danny the Fish saves from his priceless collection. They are implied to contain information on Last Contact.
