2. With the exception of the biologicaland medicalareas, efforts 
have been made to provide as broad a coverage of the Soviet 
scientific andtechnical sceneas possible. However,a physical 
science orientation resulted because the prime source of 
material, the Battelle Memorial Institute Slavic Library, is 
heavily oriented toward the physical sciences. 
3. In order to provide current, rather than historical informa- 
tion, only literature published since 1957 was used as source 
material. Since the structure of the Soviet scientific com- 
munity has beenina state of continuous flux and reorganization 
since 1957, the dates of the source material for information 
on the administrative affiliation of the various institutes are 
shown. 
Methodology 
In the early 1950's the Battelle Library, inassociation with the Battelle 
technical staff, began a systematic program ofacquiring Soviet technical pub- 
lications which paralleled the research interests of the Institute. This pro- 
gram has been continuous and has resulted in the development of extensive 
knowledge of the contents and availability of Slavic technical literature. The 
method used in guiding the acquisition program was to identify significant 
authors in selected fields, their institutional affiliations, and those journals 
in which their work was published. This method of operation resulted ina 
collation of many bits of information concerning these relationships collected 
from newspapers, technical journals, and many irregular publications. 
This collated information served as the basis for assembling the facts 
presented in the Directory, althoughit was necessaryto make countless checks 
back to the original publications. These publications are, for the most part, 
held in the Battelle Slavic Library which, because of this continuing effort, 
has become one of the most comprehensive private collections of Soviet 
published technical literature in the United States. Additional valuable infor- 
mation was obtained through the cooperation of various United States agencies 
such as the Office of International Relations of the National Academy of 
Science, and the Foreign Demographic Divisionofthe Bureau of Census, United 
States Department of Commerce.
