That web site story led me to another story on the house in the July 2nd article in the State Journal Register by Bernard Shoenberg, "Plans Underway to build replica of Lincoln's Springfield cottage".

An interesting sentence near the end of the article regarding Michael Burlingame -
"Burlingame has written more than a dozen books on Lincoln, with two more in the works. "Abraham Lincoln and Mary Todd: The True Story of their Troubled Marriage," is written and yet to be published. He’s also working on a book about Lincoln’s interactions with African-Americans, and the title will include a quote from abolitionist Frederick Douglass: "Emphatically, The Black Man’s President"
That first one will be interesting. I will be looking forward to when it gets published.
