glottolog is a bibliographic database of the world's lesser-known languages, developed and maintained first at the former max planck institute for evolutionary anthropology in leipzig, germany, and since 2015 at the max planck institute for the science of human history in jena, germany. its main curators include harald hammarström and martin haspelmath.
glottolog provides a catalogue of the world's languages and language families and a bibliography on the world's less-spoken languages. it differs from the similar catalogue ethnologue in several respects:
- it attempts to only accept languages which the editors have been able to confirm both exist and are distinct. varieties which have not been confirmed, but are inherited from another source, are tagged as "spurious" or "unattested".[note 1]
- it attempts only to classify languages into families which have been demonstrated to be valid.
- bibliographic information is provided, especially for lesser-known languages.
- to a limited extent, alternative names are listed according to the sources which use them.
the language names used in the bibliographic entries are identified by iso 639-3 code or glottolog's own code (glottocode); apart from a single point-location on a map at its geographic centre, no ethnographic or demographic information is provided. external links are provided to iso, ethnologue and other online language databases
the latest version is 4.1, released under the creative commons attribution 4.0 international license in november 2019.
it is part of the cross-linguistic linked data project hosted by the max planck institute for the science of human history.
