EXCHANGES. 
A considerable portion of the periodicals in the Smithsonian 
Library are obtained in exchange for publications of the Institution. 
During the year 138 new titles of periodicals were thus added to the 
large series of scientific journals already contained in the Smith- 
sonian deposit. There were also secured 1,062 parts to complete 
imperfect sets of publications already in the library. 
This work of completing the sets and series in the Smithsonian 
deposit is of great importance and has been carried forward with 
definite results. 
In response to requests sent to various institutions, 832 missing 
parts have been supplied to complete 124 sets of publications of 
scientific institutions and learned societies, 151 parts of 62 period- 
icals and 78 parts of 30 sets and 1 map for the series in the general 
classification. Among the more important publications received and 
sent to the deposit to complete the sets may be mentioned 73 parts 
of the “ Chetniia,” of the University of Moscow, Russia, making the 
set complete from 1869 to date; also 60 parts of the Boletin de la 
Sociedad Mexicana de Geografia y Estadistica, of Mexico City, 
Mexico, completing the set to date; and 4 sets of publications, com- 
prising 78 volumes, from Het Islenska Bokmentafelag, of Reykjavik, 
Iceland, completing the sets from 1869 to date. 
The securing of publications of historical societies in the United 
States and abroad has been continued, and many additional publica- 
tions have been obtained and transmitted to the Library of Congress. 
READING ROOM. 
The reading room has been in constant use during the year. There 
are now on file about 270 foreign and domestic scientific periodicals 
which are required by the staff of the institution and its branches 
for consultation. In view of the fact that this collection contains 
representative scientific periodicals from all parts of the world, offi- 
cers of the scientific bureaus of the various governmental establish- 
ments in Washington and students generally continue to take advan- 
tage of the opportunity to consult them.
