to the cataloo:, loaned 2,134 publications, and rendered the usual 

 reference service, especially in connection with the scientific work of 

 the Bureau. 



ASTROPHYSICAL OBSERVATORY LIBRARY 



The library of the Astrophysical Observatory has 4,487 volumes 

 and 3,726 pamphlets, largely on the major subjects of interest to the 

 Observatory. The additions in 1932 were 130 volumes and 259 

 pamphlets. The staff entered 1,209 periodicals and prepared 607 

 cards for the catalog. The loans numbered 117. 



RADIATION AND ORGANISMS LIBRARY 



The library of radiation and organisms, which is the working 

 collection of the most recently established division under the Smith- 

 sonian, numbers 194 volumes, 10 pamphlets, and 6 charts. The 

 accessions for the year were 4 volumes, 300 parts of volumes, and 1 

 pamphlet. 



LANGLEY AERONAUTICAL LIBRARY 



The Langley aeronautical library, the nucleus of which came from 

 the third Secretary of the Institution and such of his associates as 

 Alexander Graham Bell, Octave Chanute, and James Means, num- 

 bers 1,954 volumes, 1,116 pamphlets, and 5 charts. Since 1930 most 

 of it has been deposited, under its own name and bookplate, in the 

 Library of Congress. The collection, while small, contains many 

 rare items, among which are sets of earl}'- aeronautical magazines. 

 It also has files of letters, photographs, and newspaper clippings. 

 During the last fiscal year the library was increased by 46 volumes, 

 519 parts of volumes, 30 pamphlets, and 5 charts. 



NATIONAL GALLERY OF ART LIBRARY 



The library of the National Gallery of Art was given special atten- 

 tion late in the year, in connection with the work of reorganizing the 

 Smithsonian library system that has been going on for some time. 

 Increased space was provided for it and steel shelving installed, the 

 collection was sorted and roughly grouped, the sets were checked for 

 missing numbers and the numbers written for, and other steps were 

 taken preliminary to the making of a shelf list and catalog. This 

 will be the chief work of the staff during the coming year, that the 

 Gallery may have at the earliest possible moment library machinery 

 adequate to its needs. 



The accessions during the year were unusually large, numbering 

 344 volumes, 428 parts of volumes, and 93 pamphlets. The collection 

 now has 1,678 volumes and 1,509 pamphlets, chiefly on the art of the 

 United States and Europe.
