Publishing questions

ISBN numbers

The publishing industry is in the process of switching all books from having 10 digit ISBN codes to 13 digit codes. While this transition is happening, both ISBNs will be printed on your books and on any order correspondence. You can use either ISBN until January 2007, when the ten digit ISBN will become obsolete.

The DK website however, will now only display 13 digit ISBNs, but don’t worry, you can still search via both ten and 13 digit ISBNs and get the correct book.
