The work of the Bureau of Ainericaii Ethnology is conducted under act of Con- 

 gress "for coutinuing ethnologic researches among the American Indians under the 

 direction of the Smithsonian Institution." 



Two series of puhlications are issued hy the Bureau under authority of Cimgress, 

 viz, annual reports and bulletins. Th<> annual reports are authorized by concurrent 

 resolution from time to time and are published for the use of Congress and the 

 Bureau ; the publication of the series of bulletins was authorized by concurrent 

 resolution first in 1886 and more definitely in 1888, and these also are issued for the 

 use of Congress and the liureau. In addition, the Bureau siipervises the publication 

 of a series of quarto volumes bearing the title, "Contributions to North American 

 Ethnology," begun in 1877 by the United States Geographical Survey of the Rocky 

 Mountain Region. 



These publications are distributed primarily by Congress, and the portions of the 

 editions printed for the Bureau are used for exchange with libraries and scientific 

 and educational institutions and with special investigators in anthropology who 

 send their own publications regularly to the Bureau. 



The exchange list of the Bureau is large, and the product of the exchange forms 

 a valuable ethnologic library independent of the general library of the Smithsonian 

 Institution. This library is in constant use by the Bureau collaborators, as well as 

 by other anthropologists resident in or visiting Washington. 



The earlier volumes of the annual reports and the seven volumes of the " Contri- 

 butions to North American Ethnology " thus far issued are out of print. 



Exchanges and other contributions tt) the Bureau should be addressed.
