Describe the feature/enhancement

When editing mode of a book, please specify what ISBN is being used. ISBN 10 or 13. ISBN 13 can use 978 and 979 (for books after 2020)

to quote ISBN.org: “To date, 13-digit ISBNs assigned by the U.S. ISBN Agency include the 978 prefixes, which allowed systems to contain both 10- and 13-digit ISBNs for all books. However, a 13-digit ISBN starting with 979 does not have an equivalent 10-digit ISBN.”

It means that books containing just the 979 ISBN-13 number don’t have corresponding ISBN10s and can only be found on newer systems and new books published after 2020.
