The Ethnologue® is the comprehensive reference work that catalogs all the known living languages in the world today. It has been an active research project for more than 60 years. Thousands of linguists and other researchers all over the world rely on and have contributed to the Ethnologue. It is widely regarded to be the most comprehensive listing of information of its kind.
The first edition in 1951 was 10 mimeographed pages and included information on 46 languages or groups of languages. Hand-drawn maps were included for the first time in the fourth edition (1953). The publication transitioned from mimeographed pages to a book in the fifth edition (1958). Founder Dr. Richard S. Pittman continued to expand his research through the seventh edition (1969), which listed 4,493 languages.
Today the Ethnologue is published annually in three volumes. These volumes are The Languages of Africa and Europe, The Languages of the Americas and the Pacific, and The Languages of Asia.
