Abraham Lincoln is often said to be the subject of more books than anyone except Jesus. So what's left to say about the 16th president?

Plenty, according to Jonathan W. White, a professor at the University of Texas at Austin who calls himself an “accidental” Lincoln scholar. White edited Why Lincoln: Preserving an American Legacy, a new collection in which Lincoln scholars explain why they keep coming back to him. White and Ben Dickstein, showrunner and executive producer of the History Channel podcast History This Week, joined The 21st Show to talk about Lincoln's use of presidential power — including his suspension of habeas corpus during the Civil War — and what it can tell us about the presidency now.

White and History This Week host Sally Helm will continue the conversation at a live taping of the History This Week podcast at the Abraham Lincoln Presidential Library and Museum on Friday, Nov. 6. Doors open at 6 p.m., and the taping begins at 6:30. It's free, but reservations are required.

Christian McWhirter is the Lincoln Historian at the Abraham Lincoln Presidential Library and Museum. He talked with The 21st about Lincoln’s evolving views on race and contemporary evolving views on Lincoln.
