This list includes only the actual books – much of the content is actually short stories (the volumes this is the case for are noted below). If you want a thorough accounting of which stories occur in what order, down to a listing of what years they occur in, I recommend Johnny Pez’s Insanely Complete Fiction List for a more detailed reading order.

- Novel length expansion of the Asimov short story of the same name, co-written with Robert Silverberg. Although originally separate from the rest of the Asimov Universe, it was brought in by Kingsbury’s Psychohistorical Crisis, and placed here as it cannot fit anywhere before the fall of the Empire.
- Foundation’s Friends: Stories in Honor of Isaac Asimov
- Anothology of stories in the Asimov Universe written by other authors. Although the stories take place all across this timeline, they are mostly expansions of Asimov stories rather than integral parts of the series, and can thus best be read here. One story in this volume crosses over with The Stainless Steel Rat Timeline.
- Psychohistorical Crisis
- Novel by Donald Kingsbury. Although not an official sequel, it is clearly derived from the Foundation series. As noted above, it also brings in the story of Nightfall.
