At my table, we buy the books we want. System/game/language doesn't matter. If you want to use it in my game, and it is one that I do not have, then it had better fit on the 36 x 24 photocopier.
It shouldn't be the DM's duty to buy every book in the player's arsenal. The players, though, have to at least provide photocopies and have the book present at game sessions.
