There are a couple of opening books that dedicate a chapter on the Alatortsev variation: The Queen's Gambit & Catalan for Black (2001) by GM Janjgava and The Queen's Gambit Declined (2007) by IM Rizzitano. The former is a repertoire book based on the move order 3.Nc3 Be7, while the latter is not.

Besides the Alatortsev variation, there are also different ways to avoid 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5. Two of them are shown in some very recent repertoire books, both published in 2018:

• 4....Nxd5 is analyzed in Play 1.d4 d5 2.c4 e6! by GM Kornev
• The Nimzo-Indian move order is chosen in The Modernized Nimzo-Queen's Gambit Declined Systems by GM Pavlovic
