Converting Between Identifiers

Converting between these identifiers can be necessary when dealing with global distribution, especially for books. To convert between ISBN-10 and ISBN-13, you can use the following steps:

    • Add "978" at the beginning of the ISBN-10.
    • Calculate a new checksum digit based on the 13 digits.
    • Replace the ISBN-10 with the newly calculated ISBN-13.
  2. ISBN-13 to ISBN-10:
    • Remove the "978" prefix.
