126 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1926 
TECHNOLOGICAL LIBRARY 
The technological library, located in the old Museum Building, 
consists chiefly of material having to do with the arts and industries, 
together with certain classes of the natural history collection that 
are little called for, or for which there is not room in the new build- 
ing. During the year, in addition to keeping up the current work, 
the assistant in charge, with the help of those who from time to 
time took his place, continued the reorganization that was begun 
the year before. About 1,500 cards were added to the shelf list. 
The loans were 245. It is hoped that the work of reorganizing this 
library can be finished in the course of the next fiscal year. 
ASTROPHYSICAL OBSERVATORY LIBRARY 2 
The library of the Astrophysical Observatory was increased by 
105 volumes, 17 parts of volumes, 86 pamphlets, and 4 charts. The 
number of volumes bound was 124. The loans are included with 
those of the office library. 
A beginning was made in checking up the various series of 
astrophysical periodicals and supplying the missing numbers. This 
work will soon be completed. The shelf list will also be finished 
and an inventory taken. 
BUREAU OF AMERICAN ETHNOLOGY LIBRARY 
The activities of the library of the Bureau of American Ethnology 
are described in the report of the chief of that bureau, by whom the 
library is administered. 
NATIONAL GALLERY OF ART LIBRARY 
Although the library of the National Gallery of Art is adminis- 
tered as a sectional library of the National Museum and will prob- 
ably continue to be as long as the National Gallery is housed in the 
Natural History Building, it is usually thought of as one of the nine 
divisions of the Smithsonian library. As such it is given a place 
by itself in the annual report. Its accessions during the year were 
155 volumes, 479 parts of volumes, and 180 pamphlets. It now totals 
581 volumes and 665 pamphlets, a small but carefully chosen and 
valuable nucleus for the larger library soon to be collected. 
FREER GALLERY OF ART LIBRARY 
The library of the Freer Gallery of Art is restricted to the inter- 
ests represented by the collections of art objects pertaining to the 
arts and cultures of the Far East, India, and Persia and the nearer
