The first aim of this project is to provide an exhaustive list of bibliographical references of descriptive work in linguistics ('Langdoc'). For understudied languages, we aim at having references to everything available on earth, while for better-studied languages, only the most extensive works are included. A web inteface will allow browsing this reference catalogue by language families, areas, document types, or bibliographical data.
The second aim ('Glottolog') is to base definitions of 'languoids' (languages, dialects, and language families) on empirical grounds: a languoid is defined as the sum of the documents which describe it. A number of eternalnicht in discussions in linguistics, most notably the language/dialect distinction, become moot when using definitions based on collections of documents.
