Chess books about Queen's Indian Defence & Catalan Opening

The Queen's Indian Defense is a chess opening defined by the moves

1.d4 Nf6 2.c4 e6 3.Nf3 b6.

Since White's third move 3.Nf3, a move commonly played to avoid the Nimzo-Indian Defence, does not threaten to occupy the centre with 4.e4, Black has the option of playing 3...b6. Alternatively Black could play 3...Bb4+ (the Bogo-Indian Defense), 3...d5 (the Queen's Gambit) or 3...c5 (which usually leads to the Benoni Defense).
The play in the Queen's Indian is similar to that of the Nimzo-Indian. The opening is considered a hypermodern one, since Black does not strive to occupy the centre with his pawns immediately.
