Quality RPG setting books? Excellent question!
In addition to the many fine suggestions above, I'd recommend:
1) RIFTS: the game has notoriously messy mechanics, but the setting is incredibly creative. It may be worth picking up some of the supplementary stuff as well, like Atlantis, with the same caveats and kudos.
2) Space: 1889: its based on adventures in the style of the writings of Jules Verne, H.G. Wells, Edgar Rice Burroughs, and others. Simply awesome things you can do include big game hunting dinos on Venus or swashbuckling adventures on flying masted ships over the red sands of Mars.
3) Underground: a dark supers game that is one part Blade Runner, one part Mad Max and a dash of Judge Dredd.
4) Deadlands: Gunslinging and Ghosts...need I say more?
5) Godlike: a very nicely detailed supers game set in WW2.
6) Traveller: the D&D of hard sci-fi RPGs
7) Paranoia: equal parts Logan's Run and Joseph Heller's Catch-22, this setting is pure genius.
8) Dream Park: I don't usually recommend this one, but either the RPG or the Larry Niven/Steven Barnes trilogy should be a fine addition. The concept? LARPing is a spectator sport with genuine athletes and an internationally audience. Celebrity Game Masters use actors, holography and robotics for the storyline & special effects.
