How about audiobooks? You can listen to them while doing chores, driving –even right before bed as part of your wind-down routine. Some of these books are read by famous authors themselves, especially autobiographies such as Becoming by Michelle Obama. To check if the book you want has an audiobook version, simply launch the Libby app and search for the title. The word “audiobook” will appear underneath your search term if available.
If you just want to explore what is available, tap on 'Library' in the Libby app, scroll down to the yellow 'What's Available?' speech bubble and and select 'Available Audiobooks'. If you listen before bedtime, Libby can automatically pause the narration after a specific amount of time set by you. Open the audiobook and drag down the moon icon to set the sleep timer.
Short stories are also a great way to squeeze in some reading. To find them, go to Library -> Explore -> Subjects -> Short Stories in the Libby app. Some of these are also available as audiobooks!
