Welcome to today's #DFD2026 countdown. The Free format for this week is EPUB, the Open Standard for ebooks. It's very easy to create your own ebooks. All it takes is a text editor to produce HTML and XML files and a zip tool to store them. If you don't want to learn HTML and XML coding, you can use Free Software like Scribus to design and generate EPUB formats for you. Calibre can organize your ebook library. Bard incorporates FLite Text-To-Speech to read ebooks aloud to you.
