Progress has been made during the year in the preparation 

 of a Supplement to the General Catalogue, which will contain 

 the titles of all books added to the Library during the years 

 1882-1899, inclusive, but not incorporated in the Catalogue 

 during the process of printing. Seven printed Parts, contain- 

 ing the headings from " A" to " Bibi," have been delivered 

 by the printer in the course of the year. 



Thirty-seven manuscript volumes have been prepared and 

 sent to press during the year, and nine printed Parts, repre- 

 senting 44 manuscript volumes, have been delivered by the 

 printer. The revision and reprinting of the heading 

 " Periodical Publications," which was begun in 1898, has been 

 completed.

 for printing, it has been necessary to remove and re-insert
