listing of current oklahoma corporations?

Answer 1

This sort of information is something you usually need to pay for, if you get it electronically. You can go to almost any public library in Oklahoma and look in the reference section. Ask the librarian for a book of all companies in the state. If you know someone who's a student of member of the University of Phoenix library, they will have access to an electronic copy of a website called Reference USA that contains similar information. Otherwise, you'll have to most likely pay for this.
