Columbia University Press has also signed a new London house to its growing roster of international publishers for whom it handles U.S. distribution: Wallflower Press. While distribution is only a small part of Columbia's sales overall—"it's less than 10%," according to director William B. Strachan—the press was eager to add Wallflower. "There were several factors," said Strachan, pointing up the fit between the two houses, especially in reference. Among the seven books that Wallflower has published since it began, The Wallflower Critical Guide to Contemporary North American Directors, edited by Yoram Allon and Del Cullen, has done especially well. Wallflower plans to publish between 20 and 25 books a year, and many will benefit from exposure at the academic meetings and mailings that Columbia handles for its own series on film and culture, as well as Columbia's trade marketing expertise.
