ETHNOLOGUE (http://www.ethnologue.com)

The Ethnologue is a listing of the languages of the world.  It provides language information by country and includes estimates of the number of speakers, alternate names, dialects and general language background information.  It is the compilation of SIL (Summer Institute of Linguistics) field staff research.  The three-letter Ethnologue language codes have been adopted as the ISO and Registry of Language (ROL) standards.  The global people group lists use the Ethnologue extensively for their language information.  The World Christian Database (WCD) also uses the Dalby language system. The current Ethnologue is 16^th edition.  Suggested updates can be submitted to <editor_ethnologue@sil.org>.
