This book is cited by many theorists and it has inspired a lot of further works including the well-known book "Note Grouping" by Thurmond. There is a German language public domain version available at https://ia600300.us.archive.org/10/items/musikalischedyna00riem/musikalischedyna00riem.pdf. However, there seems to be no English edition available anywhere, including Amazon.com. So, my questions are:
1) Do you know of anyone who owns a copy of this book in English who could share this in some way respectful of the laws?
2) How could we proceed in order to set up a crowd-sourced or crowd-funded effort with the aim of meeting translators and funders so a public domain English edition of this book can be released made available for all?
I would appreciate your input, guys.
