### ISBN\-10 to ISBN\-13 conversion

A 10\-digit ISBN is converted to a 13\-digit ISBN by prepending "978" to the ISBN\-10 and recalculating the final checksum digit using the ISBN\-13 algorithm. The reverse process can also be performed, but not for numbers commencing with a prefix other than 978, which have no 10\-digit equivalent.


Are there any differences in ISBN-10 and ISBN-13 formatting for non-fiction books?
