Books specific to Nc3:

2."French Defence - 3.Nc3 Bb4" Lev Psakhis,Batsford Ed., ISBN: 0 7134 8841 7

4. "Franzosisch Winawer" Kindermann-Dirr, Chessgate, 2001, ISBN: 3-935748-00-0
and Anand books (chap. 6 and 7) as given above.
These books all contain interesting ideas, but I like more Khalifman's books (and I have a lot of work in the future to continue reading all games/variations) for their content and Kindermann-Dirr about the oo-Winawer, a great book (with photos,reference to key games and so on)...but mine is in german language (and difficult for me to understand well the comments

)
