In January of 2002, The Eye of the World was split into two volumes and republished as part of Tor's youth-oriented line of books:

• From The Two Rivers ISBN 0-765-34184-0
• To The Blight ISBN 0-765-34221-9

The text from the original is not abridged. FTTR has a new prologue chapter that features some of the characters a few years before the start of TEOTW; TTB includes a new glossary. Both books are illustrated.

In February of 2004, The Great Hunt was similarly published as two YA mass market paperback volumes by Starscape:

• The Hunt Begins: The Great Hunt, Volume 1 ISBN 0-765-34843-8
• New Threads in the Pattern: The Great Hunt, Volume 2 ISBN 0-765-34844-6

The books are illustrated by Charles Keegan, who also did the cover art for the YA TEOTW books. There are no extra chapters that we are aware of.
