Yes all those were short stories by Terry, I was lucky enough to find the Hard covers, but there are some great stories in them besides Pterry.
Also Troll Bridge in The Mammoth book of Cosmic Fantasy Ed.by Mike Ashley and you can find it again in After the King Ed. by Martin H. Greenberg,and if you happen to see HIDDEN TURNINGS Ed. by Diana Wynne Jones it has Turntables in the Night in it
hope this helps happy hunting.
