The library where the discovery was made:

I’m hoping that a full scan appears in the archive linked at the bottom of the page. I’m a composer and still hand-notate in a notebook. It’s so cool to the penmanship of someone writing in notebooks so quickly yet cleanly. In case you didn’t read, the contents are primarily exercises in composition where Mozart began a passage, the student continued, and Mozart corrected / guided the students work where needed. So there’s a higher percentage of Mozart in the pieces here than not. Like Brundlefly.
