The sixth series of publications is the annual report (in imperial 0(!- 

 tavo) of the I>ureau of Ethnology, i)hiced by Congress in charge of tlie 

 Smithsonian Institution. Of this series four annual volumes have been 

 published— those for 1871)-'S0, 1880-'81,.1881-'82, and 1882-'8;3— with an 

 aggregate of 2,3G9 pages, 1,821 cuts, 259 plates, and 3 maps. 



The distribution of these volumes to individuals is wholly by members 

 of Congress and the Director of the Bureau, Maj. J. W. Powell. 



7. Copyright. 



"No copyright has ever been secured on the publications of the Insti- 

 tution. U'liey are left free to be used by compileis of books without any 

 restrictions, except that full credit shall be given to the name of Smith- 

 son for any extracts which may be made from them. 



8. Use of Illustrations. 



Copies of the wood cuts used by the Institution are granted to 

 authors or publishers on payment of the actual cost of ])roduction of 

 electroty]>es, ami promise to give proper reference to the article in which 

 they originally appeared. 



9. Size of editions. 



In the first ex])eriments of the Smithsonian system of publication 

 the pro])er magnitude of the editions necessary to meet the immediate 

 and future demand could not be accurately ascertained. The number 

 of copies of the contributions theji fixed upon has since been found in- 

 ade(piate, although it was larger than that usually issu<Ml by other insti- 

 tutions. The edition has, therefore, been augmented, until at the 

 present time 1,000 copies of each article are set aside to be comljincd 

 into volumes, and an extra number, varying with the probable d(!njand, 

 struck off for separate distribution, and for sale. 



Each article is complete in itself, with se])arate paging, title, and in- 

 dex, aiul without any necessary relationship to others combined with 

 it in the same volume. 



Of the early volumes of Smithsonian Contributions, the edition, for 

 reasons already explained, was less than that of the succeeding oik-s, 

 so that complete sets can not now be furnished. 



In the year 1862 the plan of stereotyping every article printed by 



* Professor BairtVs report for 1880.
