The Collected Stories

The Collected Stories of Robert Silverberg, published by Subterranean Press, consists of nine volumes and approximately 3700 pages. But still this collection contains only about 30% of Silverberg’s science fiction and fantasy short stories (and none of his non-genre short stories).
Some of the stories that were not included in The Collected Stories can be found in other collections. However, more than 200 of Silverberg’s science fiction and fantasy short stories do not appear in any collection. In addition, there are more than 150 uncollected non-genre short stories (mysteries, adventure stories et cetera).

Expansions

Robert Silverberg has repeatedly expanded short stories into longer works, usually novels. This also includes the expansion of three short stories written by Isaac Asimov.

Fix-Ups

Wikipedia defines a fix-up as “a novel created from short fiction that may or may not have been initially related or previously published. The stories may be edited for consistency, and sometimes new connecting material, such as a frame story or other interstitial narration, is written for the new work.” Robert Silverberg has published eight such novels:
