The Victoria County History of Yorkshire, North Riding
The Victoria History of the County of York was planned to comprise five distinct sets of volumes, three of which have been completed. Work continues in Yorkshire East Riding. For the North Riding, two volumes were published in 1914 and 1923 with an index volume following in 1925.
The Yorkshire 'sets'
The first of the three Yorkshire sets, which comprised three volumes describing Yorkshire in general and an index volume, was published between 1907 and 1925. The prehistory and ecclesiastical and economic history of the county are among the topics treated in the general volumes. The topographical treatment of the county, giving more detailed and fully-referenced accounts of areas on a parish-by-parish basis, began in the North Riding. The third completed set, a single volume on the city of York, came out in 1961, after work had restarted in the 1950s with funding from the local authorities. Work in the West Riding is limited to a single township, Barlow, while work continues in the East Riding.
Volumes I and II, together with the un-numbered volume detailing the city of York, and Volume III, detailing the whole county's medieval religious houses, are on British History Online. For full access to all volumes, check your local library catalogue or your local archive.
