EXCHANGE OF PUBLICATIONS 



The collections in the library system have been built up partly by 

 the early provisions of the copyright law, partly by purchase and 

 gift, but to a very large extent by exchange, for from the first the 

 Institution and its branches have exchanged their publications for 

 those of other learned institutions and societies and for scientific and 

 technical journals and monographs. These have come to the Smith- 

 sonian libraiy by mail or through the International Exchange Serv- 

 ice, which is administered by the Institution. 



In the course of the fiscal year just closed there came to the library 

 by mail 24,594 packages and by the Exchange 1,688, each containing 

 one or more publications. These were stamped, entered, and for- 

 warded to the appropriate libraries of the system. Among the 

 notable sendings, of which there were many, was one of 331 volumes 

 and parts of Neerlandia from the Allgemeen Nederlandsch Verbond, 

 at The Hague. This was assigned to the Smithsonian deposit. 



The publications received included 4,5G5 dissertations from the uni- 

 versities of Basel, Berlin, Bern, Bonn, Breslau, Cornell, Erlangen, 

 Gand, Giessen, Greifswald, Halle, Heidelberg, Helsingfors, Jena, 

 Johns Hopkins, Kiel, Konigsberg, Leiden, Leipzig, Lund, Maiburg, 

 Neuchatel, Pennsylvania, Rostock, Strasbourg, Tiibingen, Utrecht, 

 Warsaw, and Ziirich, the Academy of Freiberg, and technical schools 

 at Aachen, Berlin, Braunschweig, Dresden, Karlsruhe, and Ziirich. 



Of the 1,808 letters written by the library staff during the year — 

 an increase of 97 over 1930 — nearly all had to do witli the exchange 

 of publications. At the close of the year this correspondence was up 

 to date. The number of publications obtained in exchange in re- 

 sponse to special requests from the various libraries of the Institution 

 was much larger than usual, or 3,590. Exchange relations for several 

 hundred new publications were entered into, particularly on behalf 

 of the Smithsonian deposit, the Langley aeronautical library, and the 

 libraries of the National Museum and Astrophysical Observatory.
