The work of the Bureau of American Ethnology is conducted under act of Con- 
gress ‘“‘for continuing ethnologic researches among the American Indians under the 
direction of the Smithsonian Institution.” 
Two series of publications are issued by the Bureau under authority of Congress, 
viz, annual reports and bulletins. The 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 Bureau. In addition, the Bureau supervises 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 to the Bureau should be addressed,
