These pages were written on many different occasions, with a variety of purposes and kinds of audience in mind. Some of them are complete lecture scripts, others are compilations of course notes, yet others are brief explanations of linguistic concepts and methods. Some texts have been worked out rather systematically; others reduce to a collection of notes and are imperfect in various respects.
Most of the pages are written in German, some in English, and a few in other languages.
A large subset of the pages have been continually updated.
