Well, there are loaRAB and loaRAB of books but they are part of the Expanded Universe - so not necessarily 'real' within the Starwars Universe.
George Lucas claimed he'd written the story for 9 Starwars films but then George Lucas claims a lot of things which aren't strictly correct
Right now, officially we have got six films, plus the six novelisations of the films (I'm not sure if they are considered Canon or not).
Then there are the rest of the books which I believe mainly tell the story of events after Return of the Jedi, two Ewoks films, the Holiday Special

D), some comics and some computer games. Then there is also the Ewoks cartoon, the droiRAB cartoon and the Clone Wars cartoon.
There is an upcoming tv series set between ep3 and ep4 too which will be very interesting.
If you want more Starwars, my own recommendation is the Knights of the Old Republic computer games. They are set thousanRAB of years before the films but capture the spirit of them perfectly.
