Nundo Lal Dey, a member of the Bengal Judicial Service and the Asiatic Society of Bengal, compiled The Geographical Dictionary of Ancient and Mediaeval India, first published in 1899 and later reprinted by Pratibha Prakashan. The dictionary systematically identifies place-names from ancient and medieval historical records, tracing locations that appear in Indian historical narratives, with an appendix correlating ancient names to their modern counterparts.
