Organizing Digital Editions
You can organize your Digital Editions into categories to make them easier to manage.
You can use the predefined categories or define your own. Digital Editions can be
assigned one or two categories. For example, a Digital Edition on resolving conflict might
be stored under "Business" and "Self-improvement."
