Forecast:A bestseller in his native Britain, Pratchett has drawn praise from such highbrow critics as A.S. Byatt and Michael Dirda. Despite a nine-city author tour, it may take a Discworld film adaptation to spark similar sales in the U.S.
Correction: The ISBN for the trade edition of The Thackery T. Lambshead Pocket Guide to Eccentric & Discredited Diseases (Forecasts, Aug. 18) is 1-892389-54-1, not 1-892389-53-3, which is for the limited edition.
