Well it's not exactly that. It's really pinpointing what characters from 1935-1939 that are considered part of DC's Earth-Two continuity. There are the obvious ones (Dr. Occult, Superman, Batman) then the less obvious ones (Slam Bradley).

As for action... It's not so much that as the serialization of the stories. They were certainly taking a page from movie serials by having stories that were about one page long and continued the next month. Which makes finding archive material of some issues difficult and giving a fragmented story :\
