When you download a book from your library or bookseller’s
web site, simply open the book from the browser download
window, and Adobe Digital Editions (ADE) will launch. If ADE
doesn’t launch automatically, start it manually, and then
drag your book onto the application icon. Or, choose File >
Add to Library to browse for the file on your computer.
When ADE opens your book, it confirms you have
permission to read it. Many books are DRM (Digital Rights
Management) protected, such as books you check out from
the library or purchase at an online book seller. If it’s not a
protected book, ADE will open it and you can begin reading.
Authorizing with an Adobe ID or Vendor ID
The first time you open a protected book, ADE will ask you
to authorize your computer. The best way to do this is to
supply an Adobe ID or Vendor ID, associating the book with
your ID. If you later open the book on another computer,
you can simply supply the same ID to open the book.
If you don’t have an Adobe ID, click the Create an Adobe ID
link. After creating the ID on the Adobe website, you can
close that browser window, return to ADE, and enter the
newly-created Adobe ID.
Authorizing without an ID
If you choose to authorize without an ID, ADE will enable
reading of the book only on your computer. You will not be
able to read it on other eReader devices or other computers
(or the same computer if you re-install). If you don’t plan on
moving your books to other computers (or re-installing), this
approach will work for you.
Bookseller-specific IDs
Some booksellers use a special form of protection where
your book is locked to the bookseller’s ID. For example,
Barnes & Noble uses this method. When you buy a book,
