Discworld Novels

[- Joy -]

I finally had time to read a Discworld novel, which has been on my reading
list for a long time, since it was recommended here ages ago.  Thinking I
was being logical, I read the one that was written first: "The Colour of
Magic".  Of course, I loved it.  Now that I'm looking to read another, I
vaguely remember hearing that they shouldn't be read in the order they were
written.  So, help me out here... Which one do I read next?  I'm torn... I
want to know what happens after they fall off the edge, I want to know more
about Unseen University... heck, I just want to know everything.  I'm sure
I'll eventually read them all, but I'd appreciate suggestions on the best
order to read them in.  Being an anal kind of person, I like to do things
properly. <grins> Thanks for getting me hooked!
