G,
Thank you for "anticipating". Looking at what you've done, I would have pulled out my remaining hair in sheer frustration!
I've got a Nook, not a Kobo, so I changed your instructions accordingly.
I did a copy/paste and gave it a try, but it did not work ... author remained unchanged after downloading to Nook.
Will double-check everything later and try again. Off to an appointment right now.
Later ...
