In 1958, Sinologist Hope Wright published a work entitled An Alphabetical List of Geographical Names in Sung China. Originally published in Paris by the Centre de Recherches Historiques of the École Pratique des Hautes Études, and reprinted as a second-generation photocopy in 1992 by the Journal of Song-Yuan Studies, the Alphabetical List is now out of print.

Wright’s compilation is the most comprehensive print source for Song geography in any language. The Digital Gazetteer of Song Dynasty China (DGSD) is a MySQL database derived primarily from the Alphabetical List. The Alphabetical List is an index to every jurisdiction in the Song (960-1276) spatial administrative hierarchy named in one or more of the following three Song texts: the Song History (宋史Song shi) Geography Monograph, the 980 Records of the Universal Realm in the Taiping Era (太平寰宇紀Taiping huanyu ji), and the 1085 Treatise on the Nine Territories in the Yuanfeng Reign (元豐九域志Yuanfeng jiuyu zhi).
