Welcome to Glottolog

Comprehensive reference information for the world's languages, especially the lesser known languages.

Information about the different languages, dialects, and families of the world ('languoids') is available in the Languoid section. The Langdoc section contains bibliographical information. You can query the bibliographical database with a normal query or a complex query involving genealogical affiliation, document type, and macro-area.

Languoid catalogue

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).

Langdoc

Langdoc is a comprehensive collection of bibliographical data for the world's lesser known languages. It provides access to more than 180,000 references of descriptive works such as grammars, dictionaries, word lists, texts etc. Search criteria include author, year, title, country, and genealogical affiliation. References can be downloaded as txt, bib, html, or with the Zotero Firefox plugin.

Glottolog will be continuously expanded and improved with the help of their users. The input of expert linguists is crucial.
