Here are a couple of links that are valuable resources for Hokum aficionados.
Blues Images and Document Records
If you want to find pre-war black blues, jazz, rags and jugband music, then Document Records can't be beat.
And, if you like the amazing graphics on the old race records ads, Blues Images publishes a calendar every single year featuring new images and a free CD of hokum music - all for a measly $19.95. The 2007 calendar is available now.
