exchanges. The periodicals currently received number about 760, of 

 which 16 were received by subscription and 744 by gifts and ex- 

 change. We have also received 200 pamphlets, giving us at the close 

 of the year a working library of 22,180 volumes, about 14,048 pamph- 

 lets, and several thousand periodicals. 



During the year there were sent to the bindery 142 volumes, and 

 84 bound volumes were received. 



In continuance of the policy of increasing the library by exchange 

 and filling in incomplete sets, letters were written for new exchanges 

 and for completing series already in the library. We have been able 

 to secure by this means many valuable and important acquisitions. 



In addition to the regular routine of cataloguing, classification, 

 ordering from book dealers, making up for binding, and keeping the 

 serial and accession records, the efforts of the librarian were devoted 

 to making a subject, author, and analytical catalogue of books that 

 are represented in the old catalogue under the author only. 



During the year there was an increasing number of students not 

 connected with the Smithsonian Institution who found the library 

 of service in seeking volumes not obtainable in other libraries of the 

 city. The library was used also by the Library of Congress and offi- 

 cers of the executive departments, and out-of-town students have 

 called upon the library for loans during the year. 



In addition to the use of its own library it was found necessary to 

 draw on the Library of Congress from time to time for the loan of 

 about 450 volumes. Numerous typewritten bibliographic lists have 

 been made for correspondents of the bureau and the Smithsonian 

 Institution. 



The Monthly Bulletin for the use of the bureau staff has been 

 continued throughout the year.
