Well, it looks like Presidents' Day has come a month early. This month's free audiobook from Tantor is "Speeches and Writings of Abraham Lincoln" by... well, you know. It will probably be free for the rest of the month, but you never know. You can find the title here
Hopefully you stocked up (like me) on fresh audio when Tantor had their various $4.99 sales this holiday season. If not they have several titles on sale this month for $6.99 a piece.
