APPENDIX 9. 

 EEPORT ON THE LIBEARY. 



SiK : 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, 1922. 



Possessing more than a million volumes, pamphlets, manuscripts, 

 and charts, acquired chiefly in exchange, the library has continued 

 its steady, ever-increasing growth. There are now, according to the 

 records, 888,128 publications deposited at the Library of Congress 

 and 156,275 belonging to the United States National Museum. Books 

 belonging to other branches of the Institution have been estimated at 

 35,000. 



Its volumes are being constantly borrowed and consulted within 

 the buildings. Interlibrary loans to accredited libraries, where 

 distance permits, are being continued, and in a number of instances 

 arrangements have been made for the photostating of pages from 

 rare volumes not permitted to leave the buildings. 



Each day typewritten lists of original scientific articles appearing 

 in periodicals received for the Smithsonian deposit in the Library 

 of Congress are prepared and sent to heads of scientific bureaus 

 under the Institution for their information and for circulation. 

 These daily bibliographical lists, begun last November at the re- 

 quest of the secretary. Dr. Charles D. Walcott, have been well re- 

 ceived from the start. Bequests from other Government bureaus 

 and research organizations have been made for copies, which it has 

 not been possible to supply. 



The facilities of the library have been taxed to the utmost since 

 the beginning of the war for information on various technical sub- 

 jects. Especially has this been so in connection with aeronautics. 

 In this one subject alone it is safe to say that the Institution, as 

 one of the sources, has been the means of saving the United States 

 Government many thousands of dollars which would have had to 

 be paid if the information relating to the prior art had not been 

 analyzed and available. 



SMITHSONIAN MAIN LIBRARY. 



As most noteworthy among the accessions of the main library 

 might be mentioned copies of the Gottingische Gelehrte Anzeigen 

 for 1758, 1760, 1808. 1813, and 1814, the gift of the Gesellschaft fiir
