Get Adobe ID
Activating Adobe Digital Editions using an Adobe ID allows you to do more with Adobe eBooks, such as downloading them on multiple computers and transferring them to supported eBook devices activated with the same Adobe ID.
IMPORTANT: You MUST have an Adobe ID to transfer an OverDrive eBook first to your computer, then to an ereader device such as a Sony or Nook.
Up to 6 computers/devices can be activated using the same Adobe ID. After the initial download of an Adobe eBook, subsequent downloads of that title can be completed on computers activated with the same Adobe ID.
Some digital publications that you check out from the library may contain digital rights management (DRM) protection that restricts the items from being shared with others. An Adobe ID gives you the right to borrow the book for a set period of time.
Important: An Adobe ID is also used by the company for its software products. If you authorize your computer with an Adobe ID, then it will always be associated with that Adobe ID. If you do not, the account is "anonymous". If you "anonymously" activate two computers, then there are two separate anonymous accounts, which cannot be merged.
Thus, the eBooks on one computer can be upgraded to "belong" to a specific Adobe ID, but the eBooks on the other cannot. If you authorize the second computer with your Adobe ID, any subsequent purchases on it are associated with that ID and transferable to any computer authorized with that ID. However, the books that were purchased on the second computer prior to being activated are forever locked to that computer.
