Series look for Fred Saberhagen’s work, published by Tandem in 1973. The type is re-used by Tor for their edition of Earth-Descended by the same author in 1981.
Later edition by another publisher re-using the same type for the same author and a different book. The “EndcapS” treatment has become a trope in mystery and science fiction, see e.g. Stranger Things.
