Edition of documents The edition of documents, the eighth and last volume of the edition of Beethoven letters, will contain non-letter written documents such as register sheets, certificates and newspaper ads from Beethoven, as well as contracts with publishing houses, property declarations, bills and minutes from court trials such as the conflict concerning Beethoven's nephew Karl. Several of these documents have not been published before. The volume will be complemented by an extensively commented index of persons, locations and works. In addition, volume 8 also comprises addenda and corrigenda concerning volumes 1 to 7 as well as a large index covering all published letters.
