The collection spans Henry Miers Elliot's career working for the Indian Civil Service from 1827 to 1853, and includes:

• Manuscripts mainly concerned with administration. These are in English and local Indian languages.
• Correspondence to Henry Miers Elliot
• Printed Material
• Visual Material, including copper-plate rubbings, agricultural drawings and a map of Baiswara.

Some of the material had previously been identified by Professor Simon Digby, Honorary Librarian to the Royal Asiatic Society (1970-1984). The information provided by him has been kept with the Henry Miers Elliot Papers.
