During the year 775 books were accessioned, of which 50 were 

 acquired by purchase, 325 by binding of periodicals, and 400 by gift 

 and exchange. The periodicals currently received number about 900, 

 of which 30 were received by subscription, the remainder being re- 

 ceived through exchange. The bureau has also received 269 pam- 

 phlets, giving at the close of the year a working library of 24,155 

 volumes, 14,777 pamphlets, and several thousand unbound periodicals. 



During the year an increasing number of visitors have applied to 

 the library for books. Information has been furnished and biblio- 

 graphic notes compiled for the use of correspondents. The officials 

 of the Library of Congress and of the Government departments have 

 also made use of the library through frequent loans during the year. 



In addition to the use of its own library, which is becoming more 

 and more valuable through exchange and by limited purchase, it was 

 found necessary to draw on the Library of Congress for the loan 

 of about 500 books.
