The Psychoanalytic Quarterly has learned retrospectively that a book review published in its April 2011 issue had previously appeared in the Fall 2010 issue of American Imago. The review, of Meg Harris Williams's book Bion's Dream: A Reading of the Autobiographies, written by James Grotstein, was published by the Quarterly in good faith as an original contribution, and we sincerely regret the error that occurred in this regard. The Quarterly apologizes to Peter L. Rudnytsky, Editor of American Imago, and to its publisher, Johns Hopkins University Press, which holds the copyright to the review.
