In carrying out the plan to effect new exchanges and to secure missing parts 
to complete sets, 2,396 letters were written, resulting in about 477 periodicals 
being added to the lists and the receipt of about 3,883 parts lacking in the sets, 
which partially filled or entirely completed the various series of publications 
in the Smithsonian deposit. In writing for the missing parts of publications 
the library has had assistance from the International Exchanges of the Institu- 
tion, but the results of these requests can not be definitely stated, as the replies 
from them were still coming in at the close of the year. In addition, the 
library has cooperated with the International Exchanges in sending out lists of 
government documents and serial publications of that class needed to complete 
the sets in the Library of Congress to the following: Argentine Republic, 
Austria-Hungary, Baden, Bavaria, Belgium, Bolivia, Bremen, Province of 
Buenos Aires, Colombia, Costa Rica, Cuba, Department of the Seine and city of 
Paris, France, Germany, Greece, Guatemala, Haiti, Free City of Hamburg, 
Grand Duchy of Hesse, Honduras, Italy, Jamaica, Japan, Malta, Mexico, Monte- 
negro, Newfoundland, New Zealand, Nicaragua, Norway, Panama, Paraguay, 
Peru, Portugal, Prussia, Roumania, Russia, Sweden, Salvador, Saxony, city of 
Vienna, Uruguay, Wurttemberg. 
A decided increase has been noted in the number of persons consulting the 
publications in the reading room, and in addition there were issued, for office 
use, 80 bound volumes of periodicals and 3,706 parts of scientific periodicals and 
popular magazines, making a total of 3,786. While the consultation has been 
chiefly by members of the staff, the various bureaus of the Government have 
availed themselves of the opportunity to use these publications and those in 
the sectional libraries of the Institution. 
The mail receipts numbered 28,059 packages. The publications contained 
therein were stamped and distributed for entry from the mail desk. About 
4,980 acknowledgments were made on the regular forms, which are in addition 
to those for publications received in response to the requests of the Institu- 
tion for exchange. 
The employees’ library.—The books added numbered 19, and of these 18 were 
purchased, while 110 volumes of periodicals were bound. The number of books 
borrowed was 1,922, and the sending of a selected number of books from this 
library to the National Zoological Park and the Bureau of American Ethnology 
has been continued. 
Art room.—tThe cataloguing of the collection of engravings in the art room 
received attention as time would allow, but there still remains a great deal to 
be done. 
Bibliography of aeronautics.—The bibliography of aeronautical literature, 
which includes the indexing of papers in periodicals and proceedings of aero- 
nautical societies, together with books and separate pamphlets on the subject, 
was completed, bringing the work up to July 1, 1909. At the close of the year 
the manuscript was ready for the printer. : 
American Historical Association.—The exchange of the annual reports of the 
American Historical Association from the allotment agreed upon for that pur- 
pose has resulted in a number of publications of historical societies throughout 
the world being added to the Smithsonian deposit at the Library of Congress.
