the volume now includes a detailed Preface by Christoph Wolff which discusses not only the works genesis but also offers an up-to-date description of the sources. For the new engraving of the musical text page-turns were reviewed and improved.
Bachs autograph is considered lost and so the main source is the original print of the collection from 1739. In collaboration with the Leipzig Bach Archive and its database Bach digital this new edition includes links to two important copies of the original print which contain hand-written entries by Bach himself.
