Go Books FAQs

  • The newest books are not listed on my device

    The list of books is sometimes not updated properly on iPhone and iPad. Pull down on the list to refresh it. If that doesn't work: Kill and restart the Go Books app, or restart your device.

  • Will books I purchase on my iPad also be available on my iPhone?

    Yes, any books you buy on your iPad will be available on your iPhone, and vice versa. Just tap on the tools icon in the top left of the app and choose ‘Restore Previous Purchases’ to make your purchases available on a different device.

  • My books are not showing up on the Mac

    You’ll also need to register your email on your iPad or iPhone, so that your books are properly associated with your email. Use Register Your Purchases on your device to do that. Please see Devices for more information.

  • Could you please add book X?

    Please let us know which Go books you'd like to see included in Go Books. We will work with the publishers and see what we can do.

    Unfortunately, there are some frequently requested books that we are not able to add due to copyright and digital rights issues, including the amazing “Lessons in the Fundamentals of Go” by Kageyama Toshiro and “Opening Theory Made Easy” by Otake Hideo. You can order these as printed books from Kiseido or Amazon.

  • Can’t read books in iOS 9

    If you’re on iOS 9 and tapping a book doesn’t open it, or the newest books don’t appear in the list of books, please try the following. Go to in Safari on your device. It should prompt you to install a certificate. Go to Details, then tap on Trust, and that should bring you to the Settings app where you can install the “ISRG Root X1” certificate. Once you’ve installed that one, restart the Go Books app, and it should load the books.
