PHOENIX (AP) — A renewed focus on social justice in the wake of police killings of Breonna Taylor and George Floyd has seen sales soar at Black-owned bookstores around the country as customers seek out knowledge from their own communities.

The stores have always served as a community space for Black people to gather and educate themselves and their communities about their culture and history. Sales increased exponentially after calls on social media in June encouraged people to spend their money at Black-owned businesses.

Bookstore owners now want people to take what they learned while reading and take action against the systems that have enabled racism and police brutality.
