Books from EBL and some other e-book providers require you to install Adobe Digital Editions-ADE-on your personal computer. This is a digital rights management system that protects the book publisher against unauthorised copying and distribution.
When you install, you must register online. After registering, you must associate any e-book you download with your Adobe ID.
To use the e-book on a different computer, you must register it to your Adobe ID. You can use your Adobe ID on up to six devices.
Detailed information about using Adobe Digital Editions is available to all users.
