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.
