Don, generally agree with your article on Lois, but it appears from my reading that you are under the impression that the "Lois Lane, Girl Reporter" series lasted for a long time in Superman Comics.  Actually it was a short-lived four-page series (ending in Superman #42), and mostly a slapstick, silly filler, much like the Adventures of Alfred in Batman.  Lois appeared very often in Superman stories after her shorts were canceled, but was never the title character again until the Showcase issues.
