Ethnologue: Languages of the World is a web-based publication that contains statistics for 7,105 languages and dialects in the 17th edition, released in 2013. Up until the 16th edition in 2009, the publication was a printed volume. Ethnologue provides information on the number of speakers, location, dialects, linguistic affiliations, availability of the Bible in the language, and an estimate of language viability using EGIDS. As of July 2013, it is the most comprehensive and accessible language catalog, although some information is dated or spurious. A project with similar goals that is still in development is the Linguasphere Observatory Register.
