Most JHU libraries e-books can be downloaded easily.

However, some of our e-books are protected by DRM (Digital Rights Management) systems, which is used by some publishers to prevent unauthorized reproduction of their books. DRM systems control the use of digital content, such as downloadable songs, DVDs and CDs, games, and of course, e-books.

The library's biggest e-book collections that have DRM are

• ProQuest E-book Central Library (formerly known as EBL), and
• EBSCO's e-books and audio books

To read DRM-protected books, you need free software called Adobe Digital Editions (ADE), or an app.
