We saw in T256708: Wikisource ebook research: How readers currently download books that people don't always understand what the different file formats mean and which one they might need. Here we're looking at other ebook services, what they offer and how they display it:
| Service | Download UI | Full download UI |
|---|---|---|
| Gutenberg (main & full) |  |  |
| Internet Archive (main & full) |  |  |
| Open Library (main) |  | |
| Manybooks (main) |  |  |
Common formats and where they work:
- EPUB - Recommended. Works on most devices.
- MOBI - Kindle and Calibre.
- PDF - Works on most devices. Easier to use on bigger screens due to lack of text reflow.
- Text - Works on most devices. No formatting.
