Just purchased an anthology, edited by George R.R.Martin and Gardner Dozois, called 'Songs of the Dying Earth' (Harper, 2009) a sort of tribute volume to Jack Vance by 23 of the greatest names in modern SF and Fantasy (it's not just me that thinks he's the 'bee's knees'!).

All the stories in the book are set in Vance's 'Dying Earth' milieu. The relevant volumes from the master, which you also might enjoy, are:

'The Dying Earth', 'The Eyes of the Overworld', 'Cugel's Saga' and 'Rhialto the Marvellous'; I think that these may have been combined in an omnibus volume recently.
