During today's Common Ground: Law Enforcement & Our Community event, Beth Waldrup gave a list of books (go about 30 minutes in to that video) as resources, and I wanted to share that list here with links.
Note: Clicking the cover will take you to an Amazon page. These are not affiliate links. Do consider, though, if you use Amazon to also make use of their Smile option. I use it to donate funds to the H&P Animal Alliance with every purchase. Alternatively, if you don't want to shop Amazon (and I totally understand why some folks don't want to) check out eBooks.com for your digital copy needs and ThriftBooks.com for used copies.
Library option: Our public library is part of the Arkansas Digital Consortium. The following books are part of that collection, although you will have to get on the waitlist: Stamped from the Beginning, How to be an Antiracist, The Hate U Give.
