REPORT OP THE SECRETARY. 93 



ACCESSIONS. 



During the fiscal year covered by this report, 29,147 packages of 

 publications were received bj' mail and 2,759 packages through the 

 International Exchange Service, making a total of 31,90G packages. 

 Some of these packages contained as many as 20 separate parts of 

 periodicals or other serial publications. About 4,737 acknowledg- 

 ments were made on the regular forms in addition to the letters 

 which were written in acknowledgment of publications received in 

 response to the requests of the Institution for exchange. 



The accessions for the Smithsonian deposit in the Library of Con- 

 gress recorded during the year numbered 3,540 volumes, 1,951 parts 

 of volumes, 15,820 pamphlets, and 366 charts, making a total of 

 21,683 publications. The accession numbers ran from 504,150 to 

 508,788, the parts of serial publications entered on the card catalogue 

 numbered 19,012, and 1,225 slips were made for completed volumes, 

 and 171 cards for new periodicals. These various publications com- 

 prised in all 52,548 separate pieces, including parts of periodicals, 

 pamphlets, and volumes. They were sufficient to fill 364 boxes, 

 which together contained approximately the equivalent of 14,560 

 volumes. In addition, 2,058 parts of serial publications secured by 

 the Institution in exchange, to complete sets, were also sent to the 

 Library of Congress. 



The practice of sending foreign public documents presented to the 

 Institution to the Library of Congress without stamping or entering 

 was continued during the year, about 4,589 publications not included 

 in any of the foregoing statistics having been sent in that manner. 



The office library received as accessions 347 volumes, 42 parts of 

 volumes, and 31 pamphlets; the Astrophysical Observator}^ 114 vol- 

 umes, 38 parts of volumes, and 86 pamphlets; and the National 

 Zoological Park 10 volumes and 9 pamphlets, making a total of 677 

 publications. 



EXCHANGES. 



Efforts to establish new exchanges and to secure missing parts to 

 complete sets of publications in the Smithsonian Library involved 

 the writing of 3,000 letters, and resulted in the addition of about 171 

 new periodicals and the receipt of about 2,058 missing parts to 

 complete volumes in the Smithsonian sets. 



New exchanges for the annual reports of the American Llistorical 

 Association from the allotment set aside by agreement for that pur- 

 pose resulted in the accpiisition of a number of publications of 

 historical societies throughout the world. These were added to the 

 Smithsonian deposit in the Library of Congress.
