I was most interested in finding out how his multivolume biography of Lincoln was coming along. According to the author, the first two volumes are with outside readers and the final two covering his presidency are in draft form. Apparently, two publishing options are still being contemplated: all four volumes in 2008 or two volumes each in 2007 and 2008 depending on scheduling issues with Johns Hopkins Press. Considering the prices of university press books, that's going to be one pricey set.
I have another Q&A scheduled for posting next week. This time it'll be with a small publisher instead of an author. Hope you enjoy it!
