Other problems can also arise. The first is when a person's lifetime has spanned different eras [Also see below].
The second is whether to use the geographic areas for the Russia/Soviet Union/Former Soviet republics, or an independent republic subdivision.
See: Russia/Soviet Union or Independent Republic Subdivision?
- For people living before 1917, use Russia.
- For those whose primary career was from 1917-1991, use Soviet Union.
- The only time LC has assigned Biography with Former Soviet republics is for books such as Who's who in Russia and the CIS countries.
A biography of Lenin
Heads of state--Soviet Union--Biography.
A biography of Lidiia Dan, a Menshevik and opponent of the tsarist regime who emigrated in 1922
A biography of Boris Savinkov (d. 1925), an opponent of the tsarist and Soviet regimes
Add: Revolutionaries--Soviet Union--Biography.
- In order to provide for consistency in headings, and to avoid the difficulty of choosing a single heading, in cases of doubt, double.
