Book Isle Tutorials: EPUB, NAS and Calibre
Begin with local ebooks, reading layout and notes, then connect WebDAV, SMB, OPDS or Calibre and check reading-data sync.
Use one of your own ebooks to learn importing and reading before connecting a remote library. Each tutorial includes a result check, so a title in a list is not mistaken for a fully available book.
Choose a tutorial for your task
- Download from WebDAV: Check your private library address and open one book.
- Browse an OPDS library: Check catalogue navigation, search and book downloads.
- Connect to Calibre Content Server: Access your computer library and check available formats.
- Sync reading data: Check progress, notes and matching books on two devices.
Book Isle does not supply books. Reading-data sync and moving book files need separate handling. Some manageable formats do not yet support full reading; check the limits stated in the tutorial and app.
