i've got, I think, all the majipoor books except that one - the first - which I believe I read about twenty years ago.

the second book in the first trilogy - Majipoor Chronicles - effectively takes the form of a collection of short stories and was, by far, my favorite of the Majipoor books. (the recent - maybe two years ago - trilogy really was kind of stinky.

Silverberg has done some great stuff over the years, though. Dying Inside was amazing. Much more recently, I enjoyed Roma Eterna - a collection of short stories stepping through both past and future history in a world where the Roman Empire didn't fall.
