Amongst those who have devoted their studies to the registers of archbishops and bishops, there has been a natural tendency to select for notice or publication those registers which will be most amply useful to scholars in the provision of historical evidence, and to set aside those volumes which are imperfect or in any way defective. The reasons for this are obviously cogent, yet complete neglect of the less satisfactory registers would be unfortunate. There is much to be learned even from the omissions and defects due to a decadent registry or a period of institutional confusion. In the hope, therefore, not only of indicating the nature of some of these less satisfactory registers, but also of showing in what directions they may include matters of interest, the registers chosen for notice in this paper are not those of Melton or Thoresby, not even that of Wolsey, which although late in date is a volume of great regularity, showing a well-conducted registry; the selected registers are those of Edward Lee (1531–44) and of his successor Robert Holgate (1544–53). They are volumes which cover the early part of the changes in ecclesiastical constitution in Tudor times, and may therefore be expected to show some reflexion, perhaps many reflexions, of the effects of those religious changes.
