Some of my favourites don't seem to've been mentioned yet (my apologies to everyone who's see me make these recommendations before):
- Jack Vance, esp. the Lyonesse Trilogy (Lyonesse:Suldrun's Garden, The Green Pearl, Madouc)
- David Lindsay's A Voyage to Arcturus (available here:

- William Morris The Well at the World's End

- while it's arguably one of the first urban fantasy novels, Susan Cooper's _The Dark is Rising_ pentalogy (Over Sea, Under Stone, The Dark Is Rising, Greenwitch, The Grey King and Silver on the Tree) are really wonderful books which don't have many of the cliche's which make much contemporary urban fantasy painful --- they're also sold as juveniles (and deserved much better than the recent wretched movie version) so should be easy to find.
Agree about Steven Brust, Michael Moorcock and a few others.
