I was catching up on some podcast listening this week, and heard the folks at Bookrageous talk about "one hit wonder" authors. One of my favorites is Ralph Ellison. A fascinating interview with Ralph Ellison has been digitized from the archives of my old work place, the Oklahoma Historical Society, and as of this writing has about 10 views. Thanks OHS for making this available to everyone to see.
You can browse Ralph Ellison's personal library on Library Thing's Legacy Library project.
