Galuppi's Op 2 transcribed in modern notation

[Jgarba]

Hi,
Recently i transcribed Galuppi's op 2 for my own enjoyment.
I have often seen scores published in modern notation of antique music protected by copyright (like Pierre Gouin, or recently i saw Gyula Pfeiffer's edition of della Ciaja work published by himslef).
If anyone is interested in this transcription i can fix the layout (now it's pretty terrible) but i need help to understand how to publish it, how i can obtain a copyright, what is viable to be published as a transcripiton (does it need to be checked?)

Thanks
Giacomo
