Frequently asked questions

How do I know if my Tor Books book is a first edition?

Check the copyright page. States 'First Edition' on the copyright page WITH a descending number line ending in 1 (e.g. '0 9 8 7 6 5 4 3 2 1' or with the lowest being 1). Tor's reliable test: the explicit 'First Edition' line PLUS the number line — both must be present for a hardcover first.

Does Tor Books use a number line?

Tor's reliable test: the explicit 'First Edition' line PLUS the number line — both must be present for a hardcover first.
