The 1908, 1909 and 1931 "New Editions" have four encyclopedic volumes covering the geography, history, economics, and administration of India, 20 volumes of the alphabetically arranged gazetteer, listing places' names and giving statistics and summary information, and one volume each comprising the index and atlas. The New Editions were all published by the Oxford University Press, Oxford, UK.
A revised form of the article on India, greatly enlarged and with statistics brought up to date, appeared as an independent volume in 1893, under the title of The Indian Empire: Its Peoples, History, and Products.
All of these were edited by Hunter, who formed the original plan of the work in 1869. A parallel series of publications known as the Imperial Gazetteer of India: Provincial Series were prepared.
