Spine of the Commercial Press single-volume 1974 edition
The Ciyuan or Tz'u-yüan was the first major Chinese dictionary linguistically structured around words (ci辭) instead of individual characters (zi字) used to write them. The Commercial Press published the first edition Ciyuan in 1915, and reissued it in various formats, including a 1931 supplement, and a fully revised 1979–1984 edition. The latest (3rd) edition was issued in 2015 to commemorate the centenary anniversary of its first publication.
