According to published accounts, to avoid litigation over a libel complaint filed in England, Cambridge University Press is destroying all unsold copies of Alms for Jihad: Charity and Terrorism in the Islamic World (2006), a book that Saudi banker Khalid bin Mahfouz claims has defamed him. The book suggests that businesses and charities associated with Mr. Mahfouz financed terrorism in Sudan and elsewhere during the 1990s.
Cambridge UP has also asked all libraries that have purchased copies to remove them from shelves. A Cambridge UP representative said he could recall, in his 23 years at Cambridge UP, only one previous incident in which the publisher had asked libraries to remove a book from their shelves.
