Rather oddly, there will be two big-name book releases for children coming out next month written by long-dead authors:
Shel Silverstein's Every Thing On It will be released on September 20th. This is the second original book to be published since Silverstein's death twelve years ago, and will feature more than 130 never-before-seen poems and drawings.
The Bippolo Seed and Other Lost Stories is a collection of seven rarely-seen stories by Dr. Seuss. The stories (which were originally published in magazines between 1950 and 1951) were collected by Seuss scholar Charles D. Cohen. The book will come out on September 27th.
