72,042 unbound papers. There were borrowed from other Govern- 

 ment Hbraries for the use of the staff a total of 4,154 titles, which 

 came mainly from the Library of Congress, and to a lesser extent 

 from the Department of Agriculture, the Army Medical Museum, and 

 the Geological Survey. 



The records of the library, all of which are kept in card form, com- 

 prise an accession catalogue, an authors' catalogue, a periodical cata- 

 logue, and a lending record. Seven hundred and eighty-two books, 

 892 complete volumes of periodicals, and 2,229 pamphlets were cata- 

 logued during the year, and the Zurich catalogue was brought up to 

 date in the matter of classification and arrangement of the cards. 

 The number of volumes bound for the library was 881. 



The new quarters and their equipment may be briefly described as 

 follows : 



The space assigned to the Ubrary in the new building, located in the 

 ground story of the northern section of the east range, consists of what 

 was originally a single room, with northern exposure, 107 feet 7 inches 

 long by 21 feet 1 inch wide, and a smaller room, facing on the east 

 court, measuring 39 feet by 21 feet 4 inches. The former has been 

 divided into three compartments for the book stacks, catalogue cases, 

 and reading accommodations, while the latter is used for office pur- 

 poses and preparatory work. All of the space is well lighted and 

 ventilated, the equipment is modern and fireproof, and the facilities 

 excellent in all respects. 



The three northern compartments are separated by fireproof walls 

 of macite, with large communicating openings. Beginning at the 

 east, and with a uniform dimension of 21 feet 1 inch between the outer 

 and the corridor wall, is the stack room, 52 feet 3 inches long, followed 

 by a small reading room, 18 feet 1 inch long, and a general reading 

 room, also containing the catalogue files, 36 feet 4 inches long. All of 

 this area is utilized to the full height of the story, tliis being accom- 

 plished by the introduction of a mezzanine floor in the stack room and 

 of galleries in the reading rooms, which are at a uniform height of 7 feet 

 11 inches above the ground floor. The furnishings throughout, in- 

 cluding slotted shelf uprights with adjustable shelves, card cases, 

 mezzanine floor and galleries, stairs and lift, are of the Art Metal 

 Construction Co.'s standard construction, and the entire work is sup- 

 ported on the ground floor, being braced laterally by comparatively 

 few connections with the walls. The material of the stacks, cases and 

 drawers is mild cold rolled steel. 



In the stack room the general arrangement of the cases is the same 

 both below and above the mezzanine floor. Single-faced stacks 

 occupy practically all the wall surfaces, while the body of the room is 

 traversed north and south by double-faced stacks, with interspaces 

 of about 3 feet. Five of these stacks are of full height, wliich is 7 feet
