text: This disrupted plans for publishing any new volumes of The Complete Works of Marx and Engels that was already in progress. It also halted distribution of other ideological works. As late as 1970, more than 8 million copies of the 4-volume set of Selected Works of Marx and Engels that had already been printed (both in cloth hardcover and paperback) remained undistributed in storage warehouses on the grounds that other works "should not interfere with learning Quotations from Chairman Mao Tse-Tung".
  On the other hand, several other works by Mao had very large printings during the same period, even though these editions were not produced in the large numbers of Quotations from Chairman Mao. These include Selected Works of Mao Zedong (in four volumes, 2.875 million copies in 14 languages), Selected Articles of Mao Zedong (various editions totalling 252 million copies), single article books, and works of poetry.
  On 12 February 1979, the Publicity Department of the Chinese Communist Party ordered to stop publishing Quotations from Chairman Mao Tse-tung.
  Foreign distribution
  In 1966, the Publicity Department of the Chinese Communist Party approved Quotations from Chairman Mao for export. To meet overseas requirements, the editors of the Chinese Foreign Languages Press made revisions necessitated by the situation. They added a "second edition preface" endorsement by Lin Biao, dated 16 December 1966 (which was torn out following Lin Biao's death and public disgrace in September 1971). On the last page, they listed the names of the publisher (PLA General Political Department) without an ISBN, the printer and distributor (both Xinhua Bookstore), and the publication year.
