There was some compensation, by the way: the abbeys were not invariably the losers. A group of books (at Lambeth) was procured to be written by a Canon of Lanthony when he was studying at Oxford (about 1415), and given to the library of his priory. We have digressed from the particular to the general. Returning to individual libraries, let us glance at the Norwich Cathedral Priory. Of this, again, we have no catalogue; it is a case in which press-marks and names of owners are our guides. Norwich has a system of press-marks consisting of a letter of the alphabet plus a Roman numeral: "N. lxviii." The press-marks of several other houses consist of just the same elements, but we can pick out that of Norwich by its size (not large) and its position (top of the first leaf of text); also there is usually added to it the name of the monk who procured it for the house, Henry de Lakenham or W. Catton--someone whose surname is the name of a Norfolk village. Over a hundred MSS. from Norwich are known to me, but they are a very small fraction of the library, as is shown by the numerals attached to the several class letters. Very few of them are as old as the twelfth century; late twelfth and particularly early fourteenth make up the bulk. I attribute this to the great fire of 1286, and I take it that then the greater part of the priory books were spoiled, and that energetic steps to refill the library were taken in the years that followed. There are more Norwich books in the University Library at Cambridge than anywhere else; it has not been proved, but I do not much doubt, that most of them were given by the chapter to Cambridge about 1574, at the suggestion of Dr. Andrew Perne, Master of Peterhouse, who was a member of the cathedral body and an enthusiast for the University Library.
