In the June 2005 issue we published a book review—written by Daniel M. Brooks—of Currassows and Related Birds by J. Delacour and D. Amadon (2004), with an updated chapter by J. del Hoyo and A. Motis. This was an unsolicited review sent to us by Dr. Brooks. After publication we learned that the same or very similar reviews by Dr. Brooks have appeared in at least four other journals; submittal of these multiple reviews was unknown to any of the five journals at the time of acceptance. The practice of multiple publication of essentially the same book review is against Conservation Biology's policy and contrary to the spirit and intent of independent collegial review. We suggest that readers consider these circumstances when assessing this book for themselves. Gary K. Meffe
