22 ANNUAL REPORT SMfTHSONIAN INSTITUTION, 1908. 



itself the largest libraiy of scientific works in this country; 3,317 

 were divided among the libraries of the Secretary's office, the Astro- 

 physical Observatory, the National Zoological Park, and the Inter- 

 national Exchanges, as expedient for purposes of administration, and 

 7,974 were deposited in the United States National Museum library. 

 Besides these, there were numerous additions to the librar^^ of the 

 Bureau of American Ethnology, which is administered separately. 

 It is estimated that an equivalent of f),5()0 volumes was transmitted 

 to the Library of Congress, comprising in actual numbers 25,524 pub- 

 lications in the form of j)arts of i^eriodicals, pamphlets, and volumes. 

 These two counts do not include public documents presented to the 

 Smithsonian Institution, sent direct to the Library of Congress as 

 soon as received, without stamping or recording ; or public documents 

 and other gifts to the Library of Congress received through the inter- 

 national exchange service, or publications requested to complete sets 

 in the Smithsonian deposit at the Library of Congress, Avhich have 

 been transmitted separately. 



As the result of a special effort to secure missing parts to complete 

 sets, 500 new periodicals were added to the lists and about 1,559 parts 

 lacking in the sets were received, which partially or entirely filled up 

 the various series of publications in the Smithsonian deposit. In 

 writing for the missing parts of publications needed to complete 

 these sets the library has had assistance from the international ex- 

 change service of the Institution. In addition the Institution has, 

 through the medium of the international exchange service, sent out 

 requests for government documents and serial publications needed to 

 complete the sets in the Library of Congress, and with this end in 

 vieAV letters have been written to Bavaria, the province of Buenos 

 Aires, Costa Rica, Greece, Guatemala, Honduras, Newfoundland, 

 Nicaragua, Japan, Russia, and Salvador. Over 3,300 publications 

 were issued during the year for consultation by members of the staff 

 and by various bureaus of the Government. 



In addition to the regular work in the library, the assistant libra- 

 rian has reconstructed the memorandum list of the engravings and 

 art collection of Mr. George Perkins Marsh, purchased in 1849, what- 

 ever catalogue may have been made having been destroyed in the fire 

 of 18()6, and has been engaged in preparing a bibliography of aero- 

 nautical literature. 



PRESERVATION OF ARCHEOLOGICAL SITES. 



I have heretofore called attention to what had been done toward 

 the preservation of archeological objects on the public domain from 

 destruction by vandals and relic hunters and toward making these 

 antiquities accessible under proper rules and regulations. Under 

 the terms of an act of Congress approved June 8, 190G, uniform regu-
