To have offline access in both web reader and our iOS and Android Apps you must do as follow:
- You need to open your reader, get and download some books to your library (downloaded).
- You can then leave your reader anytime but make sure not to log out of the reader.
- So long a you have not logged yourself out, when you access the reader in offline condition you still have full access to your downloaded books.
Of course you need to know that when you are offline, your links to outside sources such as videos from YouTube or any content which needs internet will not be available.
Authors can help by considering a number of points when they create a book in order to reduce impact of offline access when this is going to be a dominant mode of access.
