  • Please make sure you're entering only the 10 or 13 digits of the ISBN and not the label, "ISBN 10:" or "ISBN 13:." For example, if you want to register Mac OS X Leopard: The Missing Manual type in the numbers 9780596529529. I apologize that the graphic we show you on the registration page is confusing. I'll ask our web team to improve the instructions and accompanying graphic.

    And thanks for being a Missing Manual fan.
