110 ANNUAL EEPORT SMITHSONIAN INSTITUTION, 1925 



these publications come to the library direct, others through the 

 International Exchange Service, ^vith which the library is in close 

 cooperation. During the past year the library received 30,49G pack- 

 ages by mail and 2,408 through the exchanges. Especially large 

 sendings were received from Barcelona, Budapest, and AVarsaw. As 

 usual, after these packages had been opened, the items were stamped, 

 entered, and sent to the appropriate branches of the library. The 

 large number received was due partly to the special effort made by 

 the periodical and correspondence divisions in noting wants and 

 writing follow-up letters. In fact, most of the 1,181 letters sent 

 out b}'^ tlie library had to do with these wants. The result was that 

 of the 2,478 missing volumes and parts requested, 2,009 were ob- 

 tained, a gain of nearly 30 per cent over last j'^ear. Exchange rela- 

 tions were also opened with a number of new societies. 



MAIN LIBRARY 



Many of the items mentioned above were, of course, forwarded 

 day by day to the Smithsonian deposit in the Library of Congress, 

 where they were made available to the public. The number of these 

 was 7,287, of which there were 5,184 complete volumes, 1,421 parts 

 of volumes, 390 pamphlets, and 292 charts. Documents of foreign 

 governments, more or less statistical in character, to the number of 

 7,408, were also sent, without being stamped or entered^ to the 

 document division of the Library of Congress. 



Dissertations were received from various universities at home and 

 abroad, such as Basel, Berlin, Bern, Breslau, Copenhagen, Cornell, 

 Dresden, Erlangen, Frankfurt a. M., Freiburg, Ghent, Giessen, 

 Greifswald, Halle, Heidelberg, Helsingfors, Leipzig, Leyden, Lund, 

 Marburg, Paris, Pennsylvania, Strasbourg, Tubingen, Uppsala, 

 Utrecht, and Ziirich; and from technical schools at Berlin, Delft, 

 Karlsruhe, and Zih-ich. 



OFFICE LIBRARY 



The office library, which includes the publications of several 

 learned societies, the aeronautical collection, the art-room collection, 

 the employees' library, and various books, chiefly of a reference 

 nature, in the administrative offices, was increased during the year 

 by 312 volumes, 5 parts of volumes, and 4 pamphlets. Of these, 34 

 were added to the aeronautical collection. 



One of the most important additions to this library was a de luxe 

 copy of the Warner Library of the World's Best Literature, the gift 

 of Secretary Walcott ; another was Seven Log-Books Concerning the 

 Arctic Voyages of Capt. William Scoresby, sr., of Whitby, Eng- 

 land, presented by the Explorers Club of New York.
