Subject searching Since country names have been changing as fast as Rand McNally can publish new maps, catalogers have had an enormous problem trying to assign geographic subject headings to Slavic materials. In 1981, the Library of Congress decided that the Soviet Union was here to stay and mandated that the official geographic subject heading be changed for Russia. In 1992 the subject heading rule changed again. If the work was published during the Soviet period or refers to an event or person around during the Soviet period, it must also have a subject heading for Soviet Union. Double and triple geographic headings are possible.
Similar problems exist with the Czech Republic, Slovakia, Croatia, Slovenia, Yugoslavia, Belarus.
For Belarus, use Belarus or Byelorussian SSR For the Czech Republic, use Czech Republic or Czechoslovakia For Croatia, use Croatia or Yugoslavia Subject headings are even worse for Georgia, Armenia, Azerbaijan, Uzbekistan, and other former Soviet republics.

There is also full-record keyword searching.
