Is there any way to tell if an e-book I've downloaded is a pirated copy?

Yes, there are several ways to determine whether or not you have purchased a legitimate copy of the book. You can look for clues such as the publisher's name and ISBN number printed on the copyright page, or check the digital rights management (DRM) system in use by the author. Additionally, you may be able to find reviews from people who have actually bought the book online.
