Mike B notes:
The White House Historical Association has a supplement to the Historic Guide 22ND edition [PDF]. Some great photos here, especially one of the Lincoln Sitting Room I’ve never seen before!
The Lincoln Sitting Room looks great, and the President’s Dining Room is beautiful, altho I’m not crazy about the O’Keefe. There are also some nice photos of the West Wing rooms.
The WHHA site has been somewhat redone. While I was there I ordered a couple of the WHH journals I didn’t have yet.
