Ravelstein

US Viking (New York) is the true first, published 24 April 2000; the UK Viking (London) edition, ISBN 9780670891313, followed within days (retailer metadata gives 27 April 2000). The two are effectively simultaneous and both are collected, but priority rests with the US issue. Bellow's last novel. The later Penguin Classics issue (9780143107576), with a Gary Shteyngart introduction, is a 'first thus' and not a first edition.
