"Among other things, this volume contains the paperback edition of Gravity's ghost, which is included unaltered as the first part of the book. The original pages of the hardcover are reproduced with the same page numbers, though the acknowledgments, references, and index have been shifted to the end of the volume. The new edition is twice as long as the original Gravity's ghost. ... The new material was initially written as a separate book, but the story is so closely related to Gravity's ghost that it seemed more sensible to bundle the two together. The additional material, the second section of this edition is entitled Big dog... Another addition to the volume is a third section "The trees and the forest"--Preface to the Enlarged edition.
