Since many years I distribute my 1500 page free physics text
(see http:// www.motionmountain.net ) under the following
The text is free. It is a physics ebook in pdf format. You can
print a copy of the pdf file(s) for yourself, you can store any
number of copies of the file(s) on your computer(s), you can
distribute the file(s) in unmodified form, and, of course, you
can lend your printout to others or use it in teaching.
However, you are not allowed to charge money for anything
containing any part of this text; it was and remains free for
everybody to read, to print for personal use, and to store
and distribute electronically in unmodified form.
Is this roughly equivalent to the
Creative Commons Attribution-Noncommercial-No Derivative Works
licence? Should/can I switch? Thank you for any hint!
