The third edition of The Autodesk File was published in 1989 by New Riders Publishing as ISBN 0-934035-63-6. That book is now out of print. The third edition was an abridged version of the in-house second edition, with chapters shuffled around and some narrative bridges added to tell the story around the documents. This book contains everything in the third edition (except the “bridge” sections), with all the material dropped in that book restored and more than 400 pages of new documents from the years 1988–1993.
