1. "A Set of Six" and "Tales of Hearsay" are both short story collections. (Tales of Hearsay is sometimes bound together with Last Essays, hence the confusion.)
2. Five stories (The Idiots, Karain: A Memory, An Outpost of Progress, The Lagoon, The Return) don't need to be listed individually because they are the "Tales of Unrest" which you list as a collection.
