Groups of adult students meeting in classes organized by university adult education departments and the Workers’ Educational Association have produced numerous local histories and editions of records, some of them of a high standard. See, for example, Bernard Jennings, A History of Nidderdale (1967), one of the first group projects, and Joan Wayne (ed.), A Foot on Three Daisies: Pirton's Story (1987). Alan Rogers (ed.), Group Projects in Local History (1977), suggested topics that classes might tackle. Since then, other groups have begun to computerize records as an aid to analysis; for example, at Sheffield University the Fairbank Collection of surveyors’ papers, the Cutlers’ Company apprenticeship, freemen, and mark books, and local surnames have been computerized and studied in a way that a single individual would find impossible. A national survey in 1992 showed that Local History was by far the most popular subject for this sort of activity.
