A First Edition is the first ever appearance in print of a particular work after the book proof/advance copy. Most antique and rare book collectors are interested in the First Edition of a title because it is the first state that the book becomes available.
It is a common misunderstanding to think that every First Edition book comes at a premium price. It is perfectly possible to start a very good collection on a more modest budget. Have a look at our First Editions and judge for yourself!
