Last week, Book TV sat down with Arthur Schlesinger, Jr. for a conversation about the series of presidential mini-biographies he’s been editing for Times Books over the last few years, including David Greenberg‘s study of Calvin Coolidge published just last month. Now, following Schlesinger’s fatal heart attack, the cable network has moved the interview up onto this weekend’s schedule, linked with a December 2003 episode of In Depth featuring Schlesinger with host Brian Lamb. The two shows will air Saturday morning at 9 a.m. with a repeat that evening.
