In May 1822 the Leipzig publisher Carl Friedrich Peters wrote to Beethoven because he wanted to do business with him. Beethoven answered in June with a list of works which he offered Peters for publication (see HCB BBr 35). As a result they exchanged letters in which they negotiated the publication of works and prices.
To show his commitment to Peters, Beethoven declares that he never wants to let Schlesinger in Berlin publish anything anymore (and definitely not the Missa solemnis, as Schlesinger was a Jew). He is also wary of Steiner and does not want to be taken advantage of. (Sigmund Anton Steiner in Vienna had up to that point been Beethoven's main publisher. He wanted to keep control, and tried to act as an intermediary between Peters and Beethoven so as not to lose the composer.)
Beethoven's main offer to Peters concerned the Missa solemnis op. 123, for which he is also prepared to put together a piano reduction. He also offers Peters Lieder (although we do not know exactly which ones he meant) as well as the Marches WoO 18, 19, 20 and 24. Furthermore Beethoven presses for an early decision regarding the complete edition of his works.
