Beethoven's piano sonatas have appeared in innumerable editions – most of them in more than one hundred, as the collection in the library of the Beethoven-Haus in Bonn reveals. The sources for these works have also never been as readily available as they are now, as most first editions can be viewed on the Beethoven-Haus website, which also hosts scans of many important manuscript sources, as well as links to images of source materials on the websites of other archives. Thus, the question must be asked: Is there any scope for another edition of Beethoven's Piano Sonatas?
