LIBRARY. 



The library of the Smithsonian Institution is maintained for the 

 purpose of assembling a collection of periodicals and publications of 

 a scientific nature, as well as the journals and other publications of 

 scientific institutions of the world, the whole forming a library of 

 reference and research. In addition to the main bulk of titles housed 

 in the Library of Congress, and known as the Smithsonian Deposit, 

 there are 35 sectional technical libraries and 4 branch libraries — the 

 National Museum library, the Bureau of American Ethnology 

 library, the Astrophysical Observatory library, and the National 

 Zoological Park library. 



The number of accessions during the year which were added to the 

 previous collection of over half a million titles numbered 7,502. Of 

 these 2,077 were for the Smithsonian Deposit, 639 for the Smith- 

 sonian office, Astrophysical Observatory, and National Zoological 

 Park, and 4,786 for the National Museum. 



Seventy-eight titles have been added during the year to the insti- 

 tution's collections of aeronautical publications, in which continued 

 interest has been shown by aeronautical research workers in the 

 Army, Navy, and scientific institutions. Author cards for 1,722 

 titles of books in the De Peyster Collection have been made, and the 

 869 volumes on French history have been made accessible. 



In the Museum library the most important acquisition was a set 

 of catalogues of the J. Pierpont Morgan art collection, presented by 

 J. Pierpont Morgan, jr. The technological library added 346 vol- 

 umes, and the books in the sectional library, division of plants, 

 have been revised and all available works on botanical subjects 

 brought together and rendered accessible. The collection in the art 

 room, statuary, as well as books, has been carefully gone over and put 

 in thorough order.
