Campaign Creations

Hello friends, I made this account to ask one question: How or where could I find the maps used in the actual brood war or original campaign?
I want to look at them and see how the real campaign uses triggers and locations and such, so my maps may benefit. Last time I looked, I could not find the maps in any file directory on my computer, so I am assuming I need something in order to get them. Do any of you fine fellas know where to look?

Thank you so much my friend!
