Transzheldorizdat (All-Union Publishing and Printing Association of Railway Transport) was founded in 1923 as part of the larger Transpechat' (Transport Printing) of the NKPS (People's Commissariat of Transportation and Communication). In 1963, the Council of Ministers of the USSR directed Transzheldorizdat to be absorbed into the burgeoning State Transport Publishing House (Gosudarstvennoe Transportnoe Izdatel'stvo). The new publishing house also absorbed the Automobile Transport Publishing House, the Marine Transport Publishing House and the River Transport Publishing House. Transport Publishing specialized in scientific, technical, industrial, educational and reference literature concerning industrial and urban transport. It continues to operate in the 21st century as a Moscow-based business.
