recovered for several of his printed works. The German expression for personal copy, , also appears in English-language Bach-scholarship, and is used in the list below when referring to prints once contained in the personal library of Johann Sebastian Bach. During Bach's lifetime his compositions were mostly distributed amongst his immediate musical associates through manuscript copies. After his death in 1750, manuscript copies of keyboard and vocal works were made by professional copyists and distributed by musical publishing firms, especially Breitkopf (Leipzig), Traeg (Vienna) and Westphal (Hamburg). This in turn led to the appearance of printed editions of his works, beginning with the publication of Bach's four-part chorales in the second half of the eighteenth century. The fact that Bach had published representative samples of his music for keyboard instruments contributed to his fame, and to an increased demand for such works after his death. In his 1732 , Johann Gottfried Walther listed all keyboard compositions by Johann Sebastian Bach which had been printed up to that point, that is, the six partitas of Clavier-Übung I. In Bach's obituary, which was published four years after the composer's death, printed and unprinted works are listed separately: the list of engraved compositions contains eight items, all of them instrumental works, and concludes with The Art of Fugue, which had been printed shortly after the composer's death. A comparable list, starting with the same eight items, appeared half a century later in Johann Nikolaus Forkel's Bach-biography. In 1937 Georg Kinsky published an extensive study of Bach's original publications. Printed music The eight publications listed in Bach's obituary included The Art of Fugue which was in fact published shortly after the composer's death. Further, two publications with vocal music and two canons are extant. Mühlhausen council election cantatas Gott ist mein König, BWV 71, Bach's council election (Ratswahl) cantata composed for Mühlhausen in 1708, was printed that same year at the expense of the town council. Also in 1709 and 1710 Bach wrote the council election cantatas for Mühlhausen, which likewise would have been printed. These cantatas, BWV 1138.1 and 1138.2, are however lost: neither a print nor a manuscript survives. Publication The Mühlhausen council commissioned the publication of the cantatas. The parts and libretto of the Gott ist mein König cantata, printed in Mühlhausen in 1708, are extant. Mus. 11495 of the Berlin State Library, one of the surviving prints of the BWV
