SECRETARY'S REPORT 15 
A total of 71 separate volumes and pamphlets were issued during the 
past year. Among the outstanding publications to appear were Dr. 
Henry Field’s compilation in the Smithsonian Miscellaneous Collec- 
tions entitled ‘Contributions to the Anthropology of the Soviet 
Union,”’ which presents, for the first time in English, accounts of 
recent findings in this little-known area; a revised edition of the popu- 
lar handbook of the National Aircraft Collection, which is in effect a 
brief history of aeronautics from the mythical flying horses of antiquity 
to the supersonic jet planes of today; two more volumes in the famous 
series of Life Histories of North American Birds, prepared by A. C. 
Bent, bringing to 17 the number so far issued in the series; and a 
paper by Jason R. Swallen on new grasses from several countries of 
South and Central America, in the Contributions from the United 
States National Herbarium. 
The total number of copies of publications in all series distributed 
during the year was 267,491. A complete list of the year’s publica- 
tions will be found in the report of the Chief of the Editorial Division, 
Appendix 12. 
LIBRARY 
Of the 57,671 publications received by the Smithsonian library 
during the year, 7,287 came as gifts from many different donors. 
Another 17,713 were periodicals mostly received in exchange for 
Smithsonian publications from research institutions and other scien- 
tific and educational organizations throughout the world. Containing 
the record of progress in science and technology, these periodicals are 
indispensable in the prosecution of the Institution’s own work. 
Increasingly heavy demands upon reading and reference services 
of the library were noted during the year, the interlibrary loans total- 
ing 2,619 publications to 89 different libraries. The new position of 
assistant librarian in charge of the Astrophysical Observatory library 
was filled by the promotion of an acquisitions assistant. 
New exchanges arranged during the year numbered 338; 6,884 
volumes and pamphlets were cataloged, and 31,184 cards were added 
to catalogs and shelflists; 1,060 volumes were sent to the bindery, 
and 1,026 were repaired in the Museum. 
At the close of the year, the library’s holdings totaled 921,206 
volumes, more than half of which are housed in the Library of Congress 
as the Smithsonian Deposit. 
Respectfully submitted. 
ALEXANDER WETMORE, Secretary.
