The Chinese Communist Party requires that all published books be assigned a “book number” by the government; between 2003 and 2004 the General Administration of Press and Publication banned around fifty periodicals and dictionaries for using registration numbers illegally obtained from other books. In January 2004 the People’s Daily reported that two men had been sentenced to seven and nine years in prison by a court in Anhui Province for “unlawful operation of a business.” The men had published a book of love poetry using fraudulent book numbers.
