The series started as an anthology book with multiple features including Batman and Superman. As of issue 71, Superman and Batman started appearing in stories together. It becomes a Superman team-up book (like Brave & the Bold at the time for Batman) between issues #198 and 214. Superman teams up with someone other than Batman in #198-201, 203-205, 208-210, 212-214. #206 is all reprints. After two issues with the Super Sons, the Superman/Batman stories resume #217.
