BIBLIOGRAPHIC RESEARCHES 



The third volume of the " Bibliography of Aeronautics," covering 

 the years 1917 to 1919, inclusive, compiled by the assistant librarian 

 of the Smithsonian Institution, Paul Brockett, was issued during 

 the year by the National Advisory Committee for Aeronautics. The 

 first volume of this bibliography was issued in 1910 as volume 55 

 of the Smithsonian Miscellaneous Collections. 



Efforts have been made for a number of years to compile a cata- 

 logue of the Watts de Peyster collection, Napoleon Bonaparte, and 

 a bibliography of scientific and technical periodicals, but up to the 

 past few years it has not been possible to devote much time to 

 these projects. During the past year, however, Mr. Condit has been 

 able to bring together a catalogue of the rarer historical works in 

 the Watts de Peyster collection, and to prepare a classified list of 

 current foreign periodicals received for the library. The latter work 

 should not be confused with the larger plan, under way for many 

 years, for the compilation of a list of publications of learned societies 

 of the world in libraries throughout the United States. The com- 

 pletion of this project does not seem possible without the expen- 

 diture of a large sum of money, which is not at present available.
