REPORT OF THE SECRETARY 127 



The progress made on the union catalogue of the Smithsonian 

 library, which Avas kept until lately in the office reading room — the 

 room that now has become the catalogue room of the Institution- 

 was notable, especially in connection with the material in tiie Smith- 

 sonian deposit, the office library, the Langley aeronautical library, 

 and the libraries of the National IVIuseum and the Astrophysical 

 Observatory. Cards were a|so added to the catalogue for the Rock- 

 hill collection of 1,100 volumes in Chinese recently given to the Insti- 

 tution and deposited in the library of the Freer Gallery of Art. 

 This progress is shown in detail by the following statistics : 



Volumes catalogued 3, 137 



Volumes recatalogued 3, 913 



Pamphlets catalogued 1, 766 



Pamphlets recatalogued 2, 846 



Charts catalogued 504 



Typed cards added to catalogue 3,337 



Library of Congress cards added to catalogue 6, 372 



MUSEUM LIBRARY 



The library of the United States National Museum, which ranks 

 next in size and importance to the Smithsonian deposit in the library 

 system of the Institution, is composed principally of works on the 

 different branches of natural history represented in the Museum. Its 

 collections increased during the year by 3,015 volumes and 1,165 

 pamphlets, totaling more by several hundred than the increase even 

 of the year before when there was an unusually large gain in acces- 

 sions. The library now numbers 72,315 volumes and 106,881 

 pamphlets. Some of the additions came, of course, by purchase, but 

 most came, as usual, by exchange and gift. The outstanding gift, 

 which, with other gifts to various divisions of the library of the Insti- 

 tution, is described earlier in this report, was received from the 

 American Association for the Advancement of Science. 



In the course of the year 10,526 parts of periodicals were entered, 

 821 volumes and 1,039 pamphlets were catalogued, and 2,382 cards 

 were added to the shelf list. The number of books and pamphlets 

 sent to the sectional libraries was 6,683. The loans to members of 

 the scientific staff numbered 5,013, of which 2,113 were borrowed 

 from the Library of Congress and 236 elsewhere. The other loans 

 totaled 89. These were made chiefly to Government libraries, but 

 a score or more to libraries outside of Washington, including those 

 of the American Museum of Natural History, Archeological Institute 

 of America, Berkshire Atheneum, Carnegie Museum, E. I. du Pont 

 de Nemours & Co. Experimental Station, Rockefeller Institute, West- 

 field Normal School, Williams College, and the following universities : 

 Maryland, North Carolina, Princeton, and Toronto. The number of
