Archbishops' Rolls & Registers. Generally, these registers are the books in which are entered the registered copies of all the official acts of the Archbishop, institutions, ordinations, benefices, resignations, wills proved, judicial proceedings, orders after visitation, archiepiscopal property and so on. The series of York archiepiscopal registers begins in 1225 and continues with only brief gaps until the practice of keeping archbishops' registers at York ceased on 31 December 1971. During the sixteenth century as the administration of the diocese became more complicated, different archiepiscopal functions began to be recorded in dedicated registers. After the appearance of the Institution Act Books in 1545 the archbishops' registers tend to become mere repositories of the more formal documents relating to Convocation and visitation, of testamentary business of the chancery court and of legal instruments affecting churches and parishes.
Institution, Draft & Office Act Books. While at first duplicating the records of institutions within the archbishops' registers, the Institution Act Books do hold additional information. The contents of these act books are not restricted to the simple record of institutions and collations, as their description might imply, but also include ordinations, letters dimissory, caveats, licences for curates, preachers, schoolmasters, proceedings affecting disputed presentations, commissions, resignations, certificates of distance and other administrative memoranda. The Draft Act Books contain many of the same details as the Institution Act Books, however there are some differences. As the Institution Act Books started to contain more and more information, during the nineteenth century the Diocesan Registry began a series of Office Act Books that recorded the legal aspects of diocesan administration.
