Selected Staff Members. Staff members were selected for inclusion in 
the Directory on the basis of the following criteria: 
1. Academicians or Corresponding Academicians ofthe U.S.S.R. 
and of the various republics 
2. Heads of Laboratories or Departments 
3. Deans and Assistant Deans 
4, Heads of Chairs 
5. Other Staff Members who, based upon the number of their 
publications and upon other workers with whom they are 
associated (coauthors), appear to be important intheir fields. 
The names and associations of some important and even well-known 
scientists and educators may have been omitted and quite probably there are 
many more able men available in each institution than have been listed. 
Description. The descriptions of the institutions have been assembled 
from information in the publications emanating from or about a given institu- 
tion. Every precaution has been taken to assure accurate representation of 
the activities of each institutionandtoassure that no major activity was over- 
looked. However, because of the physical science orientation of the source 
materials, some inaccuracies are undoubtedly present. 
Wherever known, the educational degrees granted by the institution are 
indicated and courses of instruction are included. 
Many of the institutions listed in the Directory publish results of their 
various research efforts. Where the publication policies are known, they are 
included in the description. The transliterated form has been used in the 
descriptions since not all forms translate directlyto the common forms in the 
English language. Table 2 lists most of the publication forms used in the 
Directory and is offered for the guidance of those who may not be familiar with 
the Soviet types of literature.

Without the patience and devotionofa large staff of engineers, scientists, 
and information specialists, it would have been most difficult to compile this 
Directory. Particular note should be made of the efforts of Thomas P. Kridler,
