This is a list of Russian-language directories from the countries of the Caucasus (Armenia, Azerbaijan, Georgia) compiled by staff of the European Reading Room as a finding aid on the Library's website. These directories cover the Caucasus between the years 1935-2005. The finding aid, which represents Library of Congress holdings as of January 2020, is arranged by country/republic, then by city, and then by the year prominently displayed on the cover of the piece, which may or may not be the actual date of publication (i.e., a directory will often have one year in large print on the cover, and a different, usually earlier, year of publication elsewhere).

A very popular and useful database with the names of over 1 million localities in Europe, North Africa, the Near East, and Central Asia, as well as the Caucasus. A variety of methods for searching place names -- exactly, phonetically, sounds like, contains, etc. -- enables researchers to identify locations whose names have been changed, misconstrued, misspelled, or lost over the centuries. For each locality, a successful search result should yield its name(s) with native name in bold; its geographic coordinates, i.e. latitude and longitude; links to maps; the country in which it is located today; and the its distance and direction from a capital city.

The GEOnet Names Server (GNS) is the official repository of standard spellings of all foreign geographic names, sanctioned by the United States Board on Geographic Names (US BGN). The database also contains variant spellings (cross-references), which are useful for finding purposes, as well as non-Roman script spellings of many of these names. All the geographic features in the database contain information about location, administrative division, and quality. The database can be used for a variety of purposes, including establishing official spellings of foreign place names, cartography, GIS, GEOINT, and finding places.
