Tap the list to view titles you've tagged with a word, phrase, or emoji. Tap on the name of the tag or on an individual jacket cover to see a tile view of the titles with that tag and take action, such as borrow, read a sample or add and remove tags. 

Tap history to view your past loans. This includes books you've borrowed, plus any assignments. Resort the list by date, borrowed or alphabetically. Tap edit at the top of the screen to remove titles from your history. Clear your current history or even disable your history altogether.
