DEPARTMENT OF PRINTED BOOKS. 21 



Progress has been made with the printing of the Supple^ 

 ment to the General Catalogue, which will contain the titles 

 of all such books as were added to the Library during the years 

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

 the process of printing. Seven printed parts, containing the 

 headings under N to T and W, Pt. 1, have been printed in 

 the course of the year. 



(c) Incorporation. — General Catalogue. — 32,700 title- 

 slips and 512 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 41,0G0 

 title-slips in each copy and to add to each copy 807 new 

 leaves. 



In addition to this incorporation 112 columns and 750 

 title-slips have been remounted and relaid in each of the three 

 interleaved copies of this Catalogue : a process rendered 

 necessary by the accumulation of titles under certain 

 headings. 



The system introduced in 1889 of fortnightly incorpora- 

 tion of accessions to the Library has been carried out with 

 perfect regularity during the past year. 



Hand Catalogues. — The number of new entries made 

 in the Hand Catalogue of " Academies " was 820 ; in that 

 of "Periodical Publications," 498; in that of "Maps and 

 Charts," 754 ; in that of Music, 2901 ; and in the Hand 

 Catalogues of London and of Country Newspapers, 2,422 and 

 3,904 respectively. 



{d) Map Catalogue. — 2,318 titles have been written for the 

 Map Catalogue, and 2,190 title- slips have been incorporated 

 in each of the two copies of it. This incorporation has 

 rendered it necessary to remove and re-insert 11,572 title-slips 

 in each of two copies and to add thereto 468 new leaves. 



(e) Music Catalogue. — 11,429 titles have been written for 

 the Music Catalogue, and 13,500 title-slips have been incorpo- 

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

 has rendered it necessary to remove and re-insert 26,625 title- 

 slips in each copy and to add to each copy 303 new leaves. 



(/) Shelf Catalogue. — For this Catalogue, in which the 

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

 marks, about 25,600 have been so mounted and about 122,900 

 have been incorporated in their proper order. 



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

 — The additions and alterations in each of the three 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 40.
