Actually, I didn't know that another author(s) had done so. Can you name them, or the titles?

The original Foundation Trilogy by Isaac Asimov consisted of:
1. Foundation
2. Foundation and Empire
3. Second Foundation

Asimov then wrote four more Foundation books:
4. Foundation's Edge
5. Foundation and Earth
6. Prelude to Foundation
7. Forward the Foundation

The second trilogy was written by other authors after Asimov died:
1. Foundation's Fear by Gregory Benford
2. Foundation and Chaos by Greg Bear
3. Foundation's Triumph by David Brin
