Setting a sleep timer
To set a sleep timer, tap 
at the top right of the audiobook player. Then, choose a preset or drag the "Fine-tune" slider to set a custom timer (5-120 minutes).
Libby will save your sleep timer choice (except the end-of-chapter option). After a sleep timer is saved, tap once to use your saved timer and tap again to change it.
To cancel the sleep timer, tap and select Off. Canceling a sleep timer also deletes your saved timer.
