DEPARTMENT OP PRINTED BOOKS. 21 



The printing of the Supplement to the General Catalogue 

 has been completed. This Supplement contains the titles of 

 all such b(ioks as were added to the Library during the years 

 1882-1899, but were not incorporated in the Catalogue during 

 the process of printing. Three printed parts, containing the 

 headings under W, Pt. 2, X, Y, and Z, have been delivered by 

 the printer in the course of the year. 



(c) Incorporation. — General Catalogue. — ^5,148 title- 

 slips and 986 index-slips have been incorporated into each 

 of the three copies of this Catalogue. This incorporation has 

 rendered it necessary, in order to maintain as far as possible 

 the alphabetical arrangement, to remove and re-insert 44,65.3 

 title-slips in each copy and to add to each copy 1,039 new 

 leaves. 



The system of fortnightly incorporation of accessions 

 to the Library has been carried out with perfect regularity 

 during the past year.

 in the Hand Catalogue of " Academies " was 393 ; in that

 Newspapers, 1,199. 



(d) Map Catalogue. — 2,684 titles have been written for the 

 Map Catalogue, and 171 title-slips have been incorporated 

 into the Reading Room copy. This incorporation has rendered 

 it necessary to remove and re-insert 3,404 title-slips in the 

 same copy and to add 170 new leaves. 



(e) Music Catalogue. — 11,591 titles have been written for 

 the Music Catalogue, and 15,239 title-slips have been incorpo- 

 rated into each of the two copies of it. This incorporation

 slips in each copy and to add to each copy 502 new leaves.

 title-slips, mounted on cards, are arranged in order of press- 

 marks, about 34,000 have been so mounted and about 126,300

{g) Catalogues of Books of Reference in the Reading Room. 

 — The additions and alterations in each of the four inter- 

 leaved copies of the Catalogue of Books of Reference in the 

 Reading Room, which are requisite in order to record the 

 changes in this collection by the addition of new works and 

 the substitution of new for earlier editions, have been made : 

 the number of such additions amounts to 200. Two copies of 

 the two volumes of this Catalogue have been laid down on 

 420 new leaves and bound in four new volumes, the necessary 

 manuscript alterations in the Catalogue (about 5,000) having 

 previously been made.
