The series of photographs, representing 55 tribes, which had been 
exhibited by the New York Public Library and the Public Library

LIBRARY. 
The reference library of the bureau, which consists of 19,240 books, 
about 12,894 pamphlets, and several thousand unbound periodicals, has . 
been in continuous charge of Miss Ella Leary, librarian, assisted by 
Mrs. Ella Slaughter. During the year 708 books were accessioned, of 
which 143 were acquired by purchase and 137 by gift and exchange, 
the remaining 428 being represented by volumes of serials that 
hitherto had been neither bound nor recorded. The periodicals cur- 
rently received numbered 629, of which only 16 were obtained by pur- 
chase, the remainder being received through exchange. Of pamphlets, 
150 were acquired. During the year 1,195 volumes were sent to the 
bindery and of these 695 were bound and returned to the bureau. 
The endeavor to supply deficiencies in the sets of publications of 
institutions of learning has continued without remission. Among 
the more important accessions of this kind during the year were 
Zeitschrift der Gesellschaft fiir Erdkunde zu Berlin, 20 volumes; 
Instituto Geografico Argentino, Boletin, 10 volumes; and Kénigliches 
Museum fiir Vélkerkunde, Veréffentlichungen, 8 volumes. 
The librarian has prepared a monthly bulletin of accessions for the 
use of the staff, and has furnished information and compiled biblio- 
graphic notes for the use of correspondents. In addition to the con- 
stant drafts on the library of the bureau requisition was made on the 
Library of Congress during the year for an aggregate of 300 volumes 
for official use, and in turn the bureau library was frequently con- 
sulted by officers of other Government establishments. 
An appropriation having been made by Congress, in behalf of the 
Institution, for installing modern steel bookstacks in the eastern 
end of the large exhibition hall on the first floor of the Smithsonian 
building, and provision having been made for affording the proposed 
increased facilities to the library of the bureau, which for four and 
a half years had been installed in the eastern galleries of the hall 
mentioned, the books therein were removed in February to the gallery
