How can I search for a city name if I don't know how it was spelled during the prewar era?

City names and other geographic locations, including ghettos, camps, administrative units (such as states or provinces), countries, etc., may be searched in the Global Keywords Search using preferred terms or variant spellings. For example, today the prewar city Lwow is known as Lviv. Either spelling may be used to find the city name for your search, as well as several other variants. The Visual History Archive does not employ soundex, so you may need to try several different spellings to find the appropriate term.
