From the creators: The purpose of the project is to collect all information relating to the books of Durham Priory, manuscript and printed work inherited, given, bought or created by the monks of the Benedictine priory of Durham, its predecessors and cells.

From the creators: York’s Archbishops Registers Revealed provides free access to over 20,000 images of Registers produced by the Archbishops of York, 1225-1650, in addition to a growing searchable index of names, subjects, places and organisations. The registers are a valuable, and in many cases, unexploited source for ecclesiastical, political, social, local and family history – covering periods of war, famine, political strife and religious reformation in the Archdiocese of York and the wider Northern Province.
The site contains over 5000 entries cataloged and organized with subject headings, indexes, and searchable contents. The project also offers IIIF capability for its images.
