Well, there are five books in ITIL version 3 and they are called.... Plenty of places to find that boring stuff. Start with Wikipedia.
Back in 2009, OGC announced a revision of the ITIL books, except we are not allowed to call it a "revision": it is an "update". They are now called "ITIL 2011" and OGC no longer exists so they are produced by the British Cabinet Office. Only the five core books are revised so far (Sept 2011). They are 455 bigger, with a compete rewrite of Service Strategy, four new processes and numerous other changes - this is not a minor revision.
