titles. That this local catalogue existed, that it was used in this way, 

 and that it was far from, complete, is proved by several references 

 to it in the lists. ^ We shall designate it by the letter A. Of course 

 nothing can be ascertained about it except what our lists reveal. 



Setting aside the catalogue marked E. 4. 13,^ which is useless for 

 our purpose, since it gives no press-marks, and, for the most part, does 

 not accurately define ediLions, we turn to the T. C. D. MS., D. 1. 5. 

 This is a local catalogue, and is described in the recently issued 

 Printed Catalogue of ^Manuscripts,^ and on the back of the volume, 

 as a catalogue of Ussher's Library. It has two distinct systems of 

 press-marks. Usually the place of a book in the library is indicated 

 by a capital letter (occasionally a double letter), followed by two 

 numerals, evidently denoting respectively the press, the shelf, and the 

 position of the volume in the shelf. Eut, less fi^equently, the press- 

 mark is a small letter followed by a single numeral. This catalogue

"We next notice two volumes, which stand side by side, D. 1. 3, 4. 

 These are described in the new Catalogue,* which is in agreement 

 with the lettering on the back, as being respectively the " Catalogue 

 of TJssher's Library as given to T.C.D. in 1666," and the " Catalogue 

 of Libraiy T.C.D. 1664." jS'evertheless, it is manifest to anyone 

 who compares a few pages in the two volumes, that they are catalogues 

 of the same libraiy. D. 1. 3 is the basis of D. 1. 4, and from it the 

 latter was almost certainly, in the fii'st instance, copied. In the ti'an- 

 script a few coiTections were made in cases where the eai'lier writer 

 had deviated from strict alphabetical order, and a few entries were 

 omitted. But later on many additions were made, and the insertions 

 appear wherever space could be found for them, in complete defiance 

 of alphabetical aiTangement. Hence it comes that this catalogue is
