This is a great resource fo sho
however a sidentoe about this edition of Mozart sonatas:

It would be morally wrong to use any of these to actually learn the piece
regardless of the already large number of wrong notes and misprints and editor changes, there is also passages of 2 or more bars at parts where it is written in the wrong octave etc.
for example if you were to perform the 310 2nd movement as is written in this score you would be doing at least 99 (i counted; there might be more) things Mozart did not write.
good site for sheetmusic though as i said earlier
respect
EDIT: 100 - this isn't even wrong articulation like accents or bizzare phrasing or grace note-to-eighth written as 2 16ths. This is all out 100 incidents of incorrect notes, missing notes, lack of or added ornamentation, rolling non-rolled chords, not rolling rolled chords
