The work of tlio Bureau of American Ethnology is conducted uuder act of Con- 

 gress "for continuing etlmologic researches among the American Indians under the 

 direction of the Smithsonian Institution." 



Two series of publications arc issued by the Bureau under authority of Congress, 

 viz, annual rei>orts and bulletins. The annual reports are authorized by concurrent 

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

 Bureau; the publication of the series of bulletins was authorized l)y concurrent 

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

 use of Congress and the Bureau. In addition, the Bureau supervises the publication 

 of a series of quarto volumes l)earing the title, "Contributions to North American 

 Ethnology,'" begun in 1877 by the United .States Geographical Survey of the Eocky 

 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 

 aud educational institutions and with special investigators in anthropology who 

 send their own publications regularly to the Bureau. 



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

 a valuable ethnologic librarj" 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 first seven volumes of the " Con- 

 tributions to North Anuiricau Ethnology" are out of print. 



Exchanges aud other contributions to the Bureau should be addressed,
