The papers comprise holograph notebooks of Richardson's journeys and tours around Britain. There are notes of Yorkshire, Lancashire, Derbyshire, Nottinghamshire, London, Bath and Oxford. Richardson's antiquarian notes on historical, ecclesiastical, architectural and heraldic subjects can be found in two volumes, and include a number of pen-and-ink drawings. There is also a manuscript copy of the Memoirs of Henry Slingsby, made by Dorothy Richardson in 1790. Slingsby (1602-1658) was a royalist politician, whose memoirs were a useful source of information on the Civil War in the North of England.
The Richardson papers provide extensive scope for cultural, social, gender, art historical, antiquarian and topographical studies.
