Library loans usually follow this script:
You go onto the library's website, and log in with your user ID and
You find an ebook that you want to read, and mark it on the library site so
that they 'loan' it to you. Your user ID, date of loan and date due to be
'returned' are appended to the ebook.
The library software then sends a small file to your computer, and attempts
to activate ADE. If it's successful, you'll get a screen asking you to
'OPEN' or 'SAVE' the ebook on your computer.
You choose one of the options, ADE opens and acts according to your
choice. If your choice is 'OPEN', then the ebook will open in Reading
mode, but won't be saved to the library. If you choose 'SAVE', ADE will
put the ebook into your library, but won't open it.
What gets messed up is on your computer. If you have registered with
Adobe, and downloaded ADE with your Adobe ID, then ADE will be 'keyed in'
on that ID, and will use it when processing ebooks that you download. If
you have registered your ereader with its parent site, then the ereader can
be used with ADE. It helps a LOT if your ereader is registered with your
If you've manipulated an ebook with an unregistered copy of DE, then you're
going to have issues related to authorization. And that becomes even worse
with loaned library ebooks.
There's no easy way out. ADE keeps track of stuff it works on and uses
your ID to do that. If you haven't authorized ADE with your Adobe ID, then
whatever ID has been used is used to track the stuff. That could be the
one from the library or possibly the one from your ereader, depending on
how you've done this. It's a mess.
There are instructions in the ADE help file on how to do this the right
way, but they may not help you now.....
That makes sense. I noticed something in one of the error boxes. It appears that when you authorize ADE, a unique id is generated that is different then when I first authorized ADE using the same ID. That ID must be appended to the ebook file when the book is downloaded. This would explain why I couldn't return the ebook borrowed with the first version I had and would also explain why it wouldn't let me re-download the book I had checked out previously under the unauthorized version.
I agree it's a mess. I understand they are trying to prevent copying these books. But I think they've gone much to far.
One word - Exactly!
Whether DE has 'gone too far' is subjective. They've implemented the
industry standard their way. Amazon did it a different way, and so did
Apple. SONY, B&N and KOBO have done it also, but they're much more aligned
with the way Adobe did it.
Also, other products, such as Overdrive (used by libraries!!!), Bluefire
Reader and Calibre to name three, have implementations that will safeguard
copyrights in other ways. Wait until you run into a DRM-protected ebook
that won't let you copy it from the computer to your ereader.... One word
