The Book Thief

Australian Picador (Pan Macmillan, Sydney) 2005 trade paperback is the true first, confirmed by the Knopf copyright page and by Australian and US dealer descriptions. It precedes the first American edition (Knopf, New York, 2006) and the UK hardcovers (2007). Note that there are two 2007 UK issues, both collected: the Doubleday adult hardcover (ISBN 9780385611466) and the Bodley Head children's/YA hardcover (ISBN 9780370329215); at least one dealer reports the Doubleday issue appeared about three weeks before the Bodley Head, but that interval is single-sourced and should not be relied on. Wikipedia's infobox lists the 2005 Australian original as "Hardback & Paperback," which conflicts with the dealer consensus that no Australian hardcover first issue exists — treat the softcover as the first.
