of less scholarly interest designed primarily for the home hours of 

 the employees. 



The additions to the library in 1935 were 240 volumes, 773 parts 

 of volumes, and 22 pamphlets. The staff entered 3,448 periodicals, 

 prepared and filed 1,G83 catalog cards, classified 3,665 aeronautical 

 clippings and mounted 1,415, made 146 cards for the aeronautical 

 file, received 2,252 visitors, and loaned 2,954 publications. These 

 statistics include some for the technological library of the National 

 Museum, inasmuch as both collections are served, for the most part, 

 by the same library attendants. 



BUREAU OF AMERICAN ETHNOLOGY LIBRARY 



The library of the Bureau of American Ethnology concerns itself 

 chiefly with the primitive peoples of the Western Hemisphere, nota- 

 bly the North American Indians. It consists of 31,101 volumes 

 and 17,189 pamphlets, besides important manuscripts, vocabularies, 

 and photographs. It was increased during the year by 400 volumes 

 and 94 pamphlets. The staff cataloged 788 publications, recorded 

 3,125 periodicals, added 3,865 cards to the catalog, made 1,069 loans, 

 and rendered even more than usual reference and bibliographical 

 Fervice to the scientists of the Bureau and other investigators. The 

 regular attendants had the assistance at different times during the 

 year of two trained employees from other libraries of the Institu- 

 tion, who advanced materially the preparation of cards for the 

 Bureau's catalog, as well as for the union catalog of the Smith- 

 sonian, and began the checking of the sets of society publications, 

 with a view to obtaining needed numbers by exchange while they 

 are still available ; 81 of these were found in the duplicate collection 

 of the Institution. 



ASTROPHYSICAL OBSERVATORY LIBRARY 



The library of the Astrophysical Observatory deals largely with 

 meteorology and astrophysics. Its accessions of 57 volumes, 1,033 

 parts of volumes, and 75 pamphlets increased the collection during 

 the fiscal year to 4,624 volumes and 3,903 pamphlets. The number 

 of cards added to the catalog was 1,633. The loans were 127. 



RADIATION AND ORGANISMS LIBRARY 



The library of radiation and organisms, the youngest and smallest 

 unit in the Smithsonian library system, is a collection of 207 vol- 

 umes, 14 pamphlets, and 6 charts pertaining mainly to the radiation 

 of the sun and its effect on plant and animal life. It was increased 

 in 1935 by 6 volumes, 224 parts of volumes, and 2 pamphlets.
