Glottolog

Glottolog provides a comprehensive catalogue of the world's languages, language families and dialects. It assigns a unique and stable identifier (the Glottocode) to (in principle) all languoids, i.e. all families, languages, and dialects. Any variety that a linguist works on should eventually get its own entry. The languoids are organized via a genealogical classification (the Glottolog tree) that is based on available historical-comparative research (see also the Languoids information section).
