PUBLICATIONS. 



The Twentieth Annual Report and Part I of the Twenty-second have been issued 

 during the year, the former in March and the latter in May, 1904. The Twenty-first 

 and Part II of the Twenty-second are in i)ress. The Twenty-third was suljmitted 

 for pul)lication on February 23, and Bulletin 28 was sent to the Public Printer on 

 March 31, 1904. 



Publications are sent to two classes of recipients: First, regularly, without special 

 request, to working anthropologists, public libraries, scientific societies, institutions 

 of learning, and to other persons or institutions able to contribute to the work of the 

 Bureau publications, ethnologic specimens, or desirable data; second, to other per- 

 sons or institutions in response to special requests, usually indorsed by members 

 of Congress. During the year 1,946 copies of the Twentieth Annual Report have 

 been sent to regular recipients, and 2,500 miscellaneous volumes and pamphlets have 

 been distributed in response to about an equal numljer of special requests. More 

 than 250 of these requests have come through Congressmen, and about 500 volumes 

 have been sent in response. One hundred and fifteen copies of Part I of the Twenty- 

 second Annual Report have been sent out. 



EDITORIAL WORK. 



Mr. Herbert S. Wood has had charge of the editorial work during the year, being 

 assisted in several instances by Dr. Elljert J. Benton, Mr. E. C Farrell (courteously 

 detailed for the work by the Government Printing Office), and Mr. William Bar- 

 num. The editorial work for the year has consisted chiefly in the reading of proofs 

 of the Twenty-first and Twenty-second Annual Reports, and the preparation for 

 printing of the Twenty-third Annual Report. 



At the time of the removal of the Bureau of American Ethnology from the United 

 States Geological Survey building in 1893, the volumes belonging to the Bureau num- 

 bered about 2,500. Through exchange and purchase the growth of the library has 

 been, on the whole, satisfactory. The library now contains 12,165 bound volumes, 

 about 6,500 pamphlets, and a large number of i)eriodicals. In the purchase of books 

 care has been used to add only such works as bear on the subject of anthropology 

 with special reference to the American Indians, although volumes relating to kin- 

 dred subjects are received through exchange. 



The accessions for the year number 302 bound volumes, about 500 pamphlets, and 

 the regular issues of more than 500 periodicals. 



CLERICAL WORK. 



The clerical work of the Bureau has been intrusted largely to Mr. J. B. Clayton, 

 who on June 1, 1904, with the approval of the Civil Service Commission, received 

 the designation of head clerk. Mr. Clayton has had personal charge of the financial
