Two things the REEES researcher must contend with are transliteration and geographical names.
We use the Library of Congress transliteration scheme for Russian. Many scholarly associations and most foreign libraries use different schemes. But, we also ignore the Library of Congress rules for certain names: Tolstoy, Dostoyevsky.
The demise of the Soviet Union and other countries has spawned a number of rules affecting the use of subject terms in the catalog. These can be summarized as follows:
If the subject you are interested in occurs:
Before 1917 use Russia
Between 1917 and 1992 use Soviet Union
After 1992 use Russia (Federation)
After 1992 use Former Soviet Republics
Refers to the country that existed from 1918 to 1993. Czech Republic stands for the present sovereign nation, as well as the constitutent part of Czechoslovakia for the period 1990-1992.
The heading Slovakia is valid for the sovereign nation that came into existence on January 1, 1993, as well as for the the republic that existed 1939-1945 and the pre-1918 entity belonging to the Austro-Hungarian Empire. The heading Slovak Republic (Czechoslovakia) covering the constituent part of Czechslovakia for the period 1990-1992 remains a valid heading.
The term "Yugoslavia" applies only to:
The geographic area of the country that existed from 1918-1992
The smaller country, comprised of Serbia and Montenegro, that was left between 1992 and February, 2003
"Yugoslavia" is no longer valid as a subject for time periods after February 2003.
