APPENDIX 9. 

 REPORT ON THE LIBRARY. 



Sir : I have the honor to submit the following report on the activ- 

 ities of the library of the [Smithsonian Institution for the fiscal year 

 ended June 30, 1921 : 



The number of packages received was 27,327, an increase over 

 the preceding year of 3,577. Of these 25,156 were received by mail 

 and 2,171 through the International Exchange Service. Many of 

 the packages received through the international exchanges, it might 

 be mentioned, were exceptionally large, consisting of publications 

 issued during the years 1914 to 1920, when it was not possible to 

 send them on account of the war. 



SMITHSONIAN MAIN LIBRARY. 



In order that material received for the Smithsonian Library may 

 be made available to the public at the earliest possible moment, 

 publications have been transmitted daily, as in years past, to the 

 Smithsonian deposit in the Library of Congress. The number of 

 publications so transmitted was 6,250, composed of 4,910 complete 

 volumes, 607 parts of volumes, 721 pamphlets, and 12 charts. The 

 accession numbers extended from 534,619 to 537,229. Four thousand 

 four hundred and sixty-four foreign government documents, pre- 

 sented to the Smithsonian Institution, were transferred to the 

 Library of Congress in accordance with the established practice. 



Material from abroad has been steadily coming in, and the re- 

 ceipts for the year have been much larger than was anticipated. The 

 number of authors' reprints and theses from German universities and 

 institutes of technology has been exceptionally large, covering the 

 years 1914 to 1920. Theses were received from the universities of 

 Berlin, Breslau, Frankfurt-am-Main, Freiburg-im-Breisgau, Halle- 

 an-der Saale, Heidelberg, Kiel, Leipzig, Marburg, Zurich, Dorpat, 

 Helsingfors, Lund. Paris, Amsterdam, Brussels, Delft, Ghent, 

 Leiden, and Utrecht ; and from the institutes of technology at Berlin, 

 Braunschweig, Stockholm, Utrecht and Zurich. 



Catalogumg. — As will be seen by comparison, the cataloguing ac- 

 complished has been more than double that of last year.
