PUBLICATIONS 



The several series of publications issued by the Institution and its 

 branches constitute its chief means of carrying on the "diffusion of 

 knowledge among men", as stipulated by its founder, James Smith- 

 son. The majority of these publications are teclinical in character, 

 but many others are in popular demand, notably the Smithsonian 

 Annual Reports, which summarize scientific progress each year in 

 25 or 30 semi-popular articles by leading authorities; the bulletins 

 of the Bureau of American Ethnology on various phases of the study 

 of the Indians ; and certain of the bulletins of the National Museum, 

 such as Bent's volumes on life histories of North American birds. 

 The wider diffusion of scientific information has been aided in 

 recent years by a service of popular science news releases, based on 

 the researches of the Institution, which are widely used by leading 

 newspapers, and this j^ear by a weeklj^ radio program on Smith- 

 sonian activities put on the air by the United States Office of Educa- 

 tion in cooperation with the Institution's editorial office. 



It is gratifying to report that this year a portion of the printing 

 appropriation has been restored, so that it has been possible to resume 

 publication in a small way of the bulletins and proceedings of the 

 National Museum and the bulletins of the Bureau of American Eth- 

 nology, all of which had been practically suspended for 3 years 

 because of drastically reduced printing appropriations. This sus- 

 pension overburdened the Smithsonian Miscellaneous Collections, a 

 series supported by the limited private funds of the Institution, with 

 many papers which would normally have appeared in the other series. 



The titles, authors, size, and date of appearance of all publica- 

 tions issued during the year are listed in the editor's rex^ort, appen-
