John B. L. Tolhurst • Volume 6 of 6: Introduction to the English Monastic Breviaries • 1942
Sixth of 6 vols. See  for a description.
On pages 238-242 are listed the MSS consulted, which are far more broad-ranging than those mentioned in vol. I, including as they do customaries, and other related matter. An anticipated volume VII, of indexes and parallel tables relating to the surviving breviaries, was never issued. This volume constitutes in its own right a notable and lasting contribution to the literature on the subject.Purchase now at Boydell & Brewer
