While generally the most recognizable name of a comic is printed on the cover, the cover title can be changed for a number of reasons. For example, "Action Comics" has frequently been listed as "Action Comics featuring Superman" or "Superman in  Action Comics", or even on occasion "Supergirl in Action Comics". The official name, however, is found in the indicia, in small print inside the comics. See also.
