There can easily be several to many paperback ISBNs.
Same edition in different formats (sizes such as Trade, Mass market).
Same edition with a different publisher. Can occur serially (author changes publisher) or simultaneously (Publishers with restricted regions).
Slight changes that you'd think of as a full edition issue (even if just typos, commas) can result in a new ISBN.
The ebook might not exactly match ANY paperback or hardback edition!
