Whenever you use a new computer for eBooks from an OverDrive-powered site, you will be prompted to 'Authorize'. To enjoy eBooks on additional computers or devices, be sure to authorize each with the same Adobe ID. You may authorize up to 6 computers and/or devices per Adobe ID.
The first thing that needs to be done is to download Adobe Digital Editions either for Windows or Mac.
For more information on authorizing Adobe Digital Editions please visit the Overdrive FAQ page
