I have two books that my son had gotten for required reading for English and I can't find any isbn numbers to list them under and I searched for them by title and author and they have many versions. How should I list them?
Have you checked the page with all the publishing info as well as the cover? If you have, then I would list them under an edition with the same cover and binding if possible and just mention in the condition notes about not being able to find an ISBN.
