Minor revisions and ISBN
I did a minor revision of one of my small eBooks and generated a new ISBN which I felt obligated to use. I want to revise it again with a better cover without generating a new ISBN. Is this possible? Or should I just ignore the new ISBN?
In the last year or so I think I've generated 3 or 4 ISBNs that I haven't used.
I'd like to try different images for making covers but I don't want to generate a new ISBN every time.
