15 city public libraries provided the website Quartz the recent circulation rankings and it looks like Go Set A Watchman by Harper Lee and The Girl On The Train  are the most popular books to be checked out:

Some libraries provided Quartz with lists for July, others for August, and some provided lists that spanned multiple recent months.
