Voilà. It's just lacking a couple of the more recent ones.
Edit: Oh, nevermind, I've been beaten to it.

Oh cool I didn't realise they weren't linked together.
I have Sourcery and the colour of magic, and I thought there was one in between that I needed to read first.
Oh, no they
are linked, just not all of them are. There are only a few of the Discworld novels that could be regarded as standalone, and even with those you'll get more out of them if you've read others written before them.
The Colour of Magic and
Sourcery are both part of the Rincewind sub-series which goes in the order shown on the picture above. So yes, you should have read
The Light Fantastic after
The Colour of Magic and before
Sourcery.
Personally my favourite sub-series would probably have to be the Watch one. The Rincewind ones were what got me into
Discworld to begin with, and I still love them too, just a fraction less than the Watch ones. The Death novels are excellent too (Random Trivia: Death is the only character to appear in every
Discworld novel, if only for a line.)
