I can't access my overdrive books from library!!!

One reason for this is the use of ADE2.0 in conjuction with a Sony eReader device.

With the eReader plugged in, ADE2.0 refuses even to display library books, let alone copy them to the eReader.

This may be an issue with other eReader devices as well; ADE2.0 is riddled with such bugs.

There are lots of bugs in ADE2.0.  Try replacing ADE2.0 with the older but more reliable v1.7.2.

(You can have them both installed at once if you like.)

Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.

You're looking in the wrong place. Overdrive is not an Adobe product. This is a forum for Adobe Reader for reading PDF files on iPads and iPhones.

Do a Google search on Overdrive to find product support from the company that makes it. Good luck.
