Craig,

I have no idea of the validity of the authors claims on C-SPAN. I'm certainly no expert on the percentages freed or the motivations of the Northern slaveholders. I have discovered, what appears to be a well researched and sourced site at this URL:

Slavery in the North
http://www.slavenorth.com/index.html

I think I'll be doing some reading and perhaps many of us on this site should visit this site to understand better the Emancipation movement in the North.

Thanks for your response.

Jim
