56 ANNUAL REPOET SMITHSONIAN INSTITUTION, 19 3 4 



22,020 packages, each containing one or more publications. Of 

 these, 20,044 came by mail and 1,976 through the International 

 Exchange Service, which is administered by the Smithsonian. Es- 

 pecially generous sendings were received from the Academic Malgache, 

 Tananarive; the Deutsche Gesellschaft der Wissenschaften und 

 Kiinste fiir die Tschechoslowakische Republik, Prag; the Elisha 

 Mitchell Scientific Society, Chapel Hill ; the Fiirstlich Jablonowskische 

 Gesellschaft der Wissenschaften, Leipzig; the Historische-Anti- 

 quarische Gesellschaft, Basel; the Societatea de Stiinte din Cluj, 

 Cluj; the Societe Scientifique du Chili, Santiago; the Societe Zoolo- 

 gique de France, Paris; the Societe des Amis de l'Universit6 de 

 Strasbourg, Strasbourg; and the Wochenschrift fiir Aquarien und 

 Terrarienkunde, Braunschweig. Four of these went far toward com- 

 pleting important sets in the Smithsonian deposit and six in the 

 library of the National Museum. Among the exchange items were 

 7,776 dissertations from the universities of Basel, Berlin, Bern, Bonn, 

 Breslau, Budapest, Cornell, Erlangen, Freiburg, Giessen, Greifswald, 

 Halle, Heidelberg, Helsingfors, Jena, Johns Plopldns, Kiel, Konigs- 

 berg, Koln, Leipzig, Liege, Lund, Marburg, Neuchatel, Pennsylvania, 

 Rostock, Strasbourg, Tubingen, Utrecht, Wiirzburg, and Zurich, the 

 Academy of Freiberg, and technical schools at Berlin, Braunschweig, 

 Dresden, Karlsruhe, and Zurich. The number of letters written by 

 the library was 2,482, most of which had to do with its exchange 

 activities, its reference work for outside correspondents, and its 

 acknowledgment of gifts. It obtained 4,114 volumes and parts in 

 response to special requests from the various libraries of the Institu- 

 tion. It entered into 238 new exchanges, more than one-half of which 

 were in the interest of the libraries of the National Museum and 

 National Gallery of Art. It may be added that most of these pub- 

 lications were obtained and most of the new exchanges arranged for 

 without drawing further on the stock of Smithsonian publications. 

 It should also be said in passing that steps were taken late in the year 

 to increase this supply, as well as that of the National Museum, very 

 materially when the library staff, in collaboration with members of 

 the division of publications, sorted and sent back to stock thousands 

 of pieces— many of them out of print — that had been returned as 

 duplicates from libraries throughout the country. This is the 

 second joint effort of the land during the last 2 years and each has 

 both added substantially to the publications available for exchange 

 distribution and brought to light hundreds that were needed in the 

 regular library sets.
