I started learning the piano in the late 80s, just over 30 years ago. At this point almost all the editions used notation that separated hand position by stave, or at least all the notes relating to one hand remained on the same stave. However, in the last 20 years i noticed that whenever I went to buy new music almost all editions mixed notes for one hand between the staves. Does anyone know why this happened? Was it the prevalence of a particular notation software? Below I'm going to give a couple of examples to explain the difference
Beethoven's Pathetique 1 (Traditional):

Beethoven's Pathetique 1 (Recent):

Here's a second example from the slow movement

I find the change quite frustrating, because I'm finding it is hindering my ability to sight read and learn new pieces, for no good reason. Furthermore, I find it very hard to explain to shops and it's becoming harder and harder to find the notation in the way i prefer. The only option i can find is hoping a copy turns up at a charity shop, which is a pretty poor strategy when you're looking for a specific piece.
If anyone knows if there is a specific name for the difference in notation styles that would go some way to helping. From a more academic perspective I'd be interested to know if anyone knows why there's been a shift in notation? Has anyone else found this to be a problem as well?
Many thanks
