The Bayerisches Wörterbuch (Bavarian Dictionary), published by the Commission for Dialect Research, covers the vocabulary of the Bavarian dialects from the early Middle Ages up to the present day. While the linguistic forms from the past are documented in literary sources, present-day Bavarian is ascertained mainly by written interviews with dialect speakers. In an operation aimed at expanding and improving the dialect material collected between the wars, about 500 informants from Upper Bavaria, Lower Bavaria, and the Palatinate are providing details about the factual connections, the use and the meaning of words and idioms. Volume 1 A – Bazi was completed in 2002. By 2007 four more fascicles (up to "bissig") were available.
A one-volume Handwörterbuch von Bayerisch-Franken (Concise Dictionary of Bavarian Franconia) was compiled in Bayreuth and published in 2007; it contains a selection of relevant dialect words. The complete dialect collections are to be turned into a database and made available on the Internet.
