In 2007, Derrick and Ramunda Young launched Mahogany Books, an online-only retailer that specializes in books “written for, by, or about people of the African Diaspora.” Ten years later, the husband-and-wife duo opened the doors of their brick-and-mortar store in Anacostia, a historically African-American neighborhood in Southeast Washington, D.C. You can purchase books online, but also make sure to check out their blog, Black Books Matter, for staff recommendations and curated booklists.
