A Guide to Desktop Linux in 2025

System requirements:

• Computer (Windows; MacOS X; Linux): Install the free reader Adobe Digital Editions prior to download (see eBook Help).
• Tablet/smartphone (Android; iOS): Install the free app Adobe Digital Editions or the app PocketBook before downloading (see eBook Help).
• E-reader: Bookeen, Kobo, Pocketbook, Sony, Tolino and many more (not Kindle).

The file format ePub works well for novels and non-fiction books – i.e., „flowing” text without complex layout. On an e-reader or smartphone, line and page breaks automatically adjust to fit the small displays.
This eBook uses Adobe-DRM, a „hard” copy protection. If the necessary requirements are not met, unfortunately you will not be able to open the eBook. You will therefore need to prepare your reading hardware before downloading.

Please note: We strongly recommend that you authorise using your personal Adobe ID after installation of any reading software.
