Anything by Victor Mollo, Right Through The Pack By Robert Darvas, Why You Lose at Bridge by S.J. Simon, the Jake Winkman books by Don von Elsner and The Bridge Bum by Alan Sontag are my go to reads in bridge.
For technique, it is hard to beat anything by Eddie Kantar, Rixie Marcus or Terrence Reese. And do not forget Watson's {lay of the Hand.
For practical, easy to understand concepts, of Mike Lawrence’s books. When I was starting out, I liked to read his Play Bridge With Mike Lawrence and Play a Swiss Teams of Four with Mike Lawrence before heading to a regional tournament – his discussion of the thought process of evaluating and re-evaluating a hand within the matchpoint and IMP formats is second to none, and it is very much like he is whispering his thought processes over the course of a matchpoint or series of matches.
