The Lost Barkscrolls was an extra book in The Edge Chronicles series by Paul Stewart and Chris Riddell. It contained four short stories about the Edge. The premise was that a young scholar from the Third Age had stumbled upon four forgotten old barkscrolls in the Great Library of the Free Glades, hence the book's name. In The Immortals, It was explained that the young scholar had been Zelphyius Dax. Sadly, this book is now out of print.
