This weekend, C-SPAN is featuring three Lincoln-related lectures as part of American History TV. The lectures will focus on the 1860 and 1864 elections. (Evidently the theme of the weekend is 'presidential elections.')
Two of the lectures are from previous Lincoln Forum events: one by David Long on the 1860 election and one by Joseph Glatthar on the 1864 election. There is also a lecture on Lincoln and Jefferson Davis by Bruce Chadwick, whose most recent book is on the 1860 election.
The lectures will run several times this weekend on C-SPAN 3.
