Georgia is a part of the Caucasus region, located at the intersection of Eastern Europe and Western Asia. It is bounded to the west by the Black Sea, to the north and east by Russia, to the south by Turkey and Armenia, and to the southeast by Azerbaijan. Georgia covers a territory of 69,700 square kilometres (26,911 sq mi), and its approximate population is about 3.716 million. Georgia is a motherland of Iberian or Kartvelian languages: Georgian, Svan, Megrelian and Laz, a language family native to the South Caucasus. This diverse collection is devoted to a wide range of linguistic works, such as descriptive studies of the Kartvelian languages and Georgian sign language, along with some theoretical contributions, dialectology, lexicography, psycholinguistics and computational linguistics, as well as history, ethnography, religion and educational issues. These articles are not only the best studies of Kartvelology but also clearly show its contribution to world science.
