This series contains the research notes, correspondence, manuscripts and photographs compiled by Benthall, Nicolson and Sunderland in relation to their respective research on the artist, John Hamilton Mortimer.
Sunderland kept the material created by Benthall as a separate entity and it has been preserved as such (see catalogue reference JNS/1/1). However, whilst much of Nicolson's research notes remain distinct (see JNS/1/2), some of the material was incorporated, by Sunderland, into his own files. Where this is the case, it has been noted in the catalogue descriptions.
Whilst much of the material in the archive was used to inform Sunderland's catalogue on Mortimer, it also includes - within the files of correspondence and research notes in particular - a considerable amount of information that remains unpublished. There is also material relating to Sunderland's work post publication including, in particular, corrections and queries from other scholars and collectors.
