Leo Okinshevich, 82, a former professor and legal consultant in his native Russia and in Europe and a retired cataloger and translator for the Library of Congress, died Friday at his home in Hillcrest Heights. He had Parkinson's Disease.

Born in St. Petersburg, now Leningrad, Russia, Mr. Okinshevich served as a second lieutenant in the Russian Army after graduating from high school. In 1921, he earned a law degree from the University of Kiev. He then worked as a research scholar with the Ukrainian Academy of sciences until 1934, when he became a professor at the Nezhin Pedagogical Institute and a legal consultant in Kazakhstan and Smolensk.

During World War II, he worked at the Institute of Regional Studies in Kiev before being sent to a labor camp in Eastern Europe during the German occupation of the Ukraine. After the war, Mr. Okinshevich was a professor in Prague and Munich before immigrating to the United States in 1949.

He worked as a Senior Fellow in Columbia University's Research Program on the U.S.S.R. in New York City before moving to this area and joining the Library of Congress in 1954. He was a senior subject cataloger and translator on the Library's Cyrillic Bibliographic Project in the Aerospace Technology Division before retiring in 1969.

His publications include two bibliographical works in his field, the two-volume "Latin America in Soviet Writings," published in 1966, and "U.S. History and Historiography in Post-War Soviet Writings, 1945-1970," published in 1976.

Survivors include his wife, Vera Nazakevich Okinshevich of Hillcrest Heights, and a stepson, George Myro of Berkeley, Calif.
