Soviet
astronomers have long been in the forefront of variable star research. Much of
the resulting literature is readily available in the United States only to
those who combine some familiarity with the language with access to large
observatory libraries. Fortunately, the single most valuable contribution to
the literature from the Soviet Union, the "General Catalog of Variable
Stars" (Third Edition, 1969-70), is available with English translation
from AAVSO Headquarters. This three-volume compendium, updated periodically
with supplements, is the result of the considerable labors of a group at the
Sternberg State Astronomical Institute of the Moscow State University directed
by B. V. Kukarkin. Two other imporartnat publications by the same institution
are the "Catalog of Suspected Variable Stars" and the journal
"Variable Stars".
