Former identifier for a book (edition), ten digits. Used for all publications up to 2006 (convertible to ISBN-13 for some online catalogs; useful for old books or fac-similes not reedited since 2007).
: converting an old ISBN-10 to ISBN-13 requires adding a "978-" prefix, but ALSO recomputing the last check digit with a different algorithm; not applicable to books published since 1 January 2007 (using ISBN-13 only, possibly with different prefixes)
: specific editions should be used with instances of ‘version, edition or translation’ (Q3331189); if necessary, create a new item and link via ‘has edition or translation’ (P747)
: Audiobooks does not use the ISBN system, If the item is about multiple editions of a literary work then those should be split into their own seperate items
