I'll toss in a couple of others. One is a novella called Great Work
of Time, by John Crowley, which has been published on its own and also
as part of a collection called "Novelty". It concerns the efforts of
a group of time travellers to extend, preserve, and further civilize
the British Empire, and the unintended consequences of their actions,
which include wizards, dinosauroid servants, and other, more
disquieting things.
The other is a World Fantasy Award winner called Talking Man, by Terry
Bisson, which concerns a Kentucky Tobacco farmer, his daughter, her
lover, the extinction of the universe, and the end of time.
I really liked both of them...
