TumbleBooks' official website states the service is available in more than 30,000 schools and libraries worldwide. While TumbleBooks was created for use in libraries, each local government decides whether to purchase access on a city- or statewide basis.
In Virginia, TumbleBooks is available at all public libraries for visitors with a valid library card. By comparison, Portland, Oregon and East Brunswick, New Jersey, offer access to TumbleBooks for residents, but the service may not be available for other cities in those states.
TumbleBooks provides remote access for member libraries and their patrons. Readers can view TumbleBooks from an Internet-enabled device at home, if they have a valid account with a participating library.
