Chronologisches Wörterbuch des deutschen Wortschatzes. Band 2 Der Wortschatz des 9. Jahrhunderts: (Titelabkürzung: ChWdW9)

In this chronological dictionary, the vocabulary of Old High German is sorted by periods, regions and text-types; in addition, vernacular insertions in Latin texts are registered as far as possible. An evaluation section lists which Old High German words appear in the 9th century at all, and which occur there for the first time. This makes it possible for the vocabulary to be examined and described systematically.
