Twenty-five Lebanese Shiite publishing houses have been barred from exhibiting books during the annual fair in Manama on 17 March 2010. Al Wassat daily newspaper reports that although a black list has been issued by the Bahraini authorities, the publishing houses are yet to be officially notified. The Bahraini Ministry of Information denies responsibility for the ban and the Bahrain Centre for Human Rights suggest it may have been issued by  the National Security Apparatus.
