To mark your place in a book in the app:
- Switch to "mini view" mode and a transparent "bookmark" will appear between the current pages you are viewing (use the pinch gesture to switch out of "full screen" mode to "mini view")
- Once you tap on the bookmark, it will turn red and mark your place
- The next time you open that book, it should take you to the bookmarked page
Note: The bookmarking feature is only available on iOS and Android mobile apps.
