While surfing around the web I found an unusual website. It's called "The Generic Radio Script Library" and it has scripts from many shows.Their site says it has the scripts for 171 shows (including Suspense, Candy Matson, Amos and Andy and more. I found one script for an episode that doesn't exist anymore (Candy Matson - The Black Cat) so you might find a new episode that way.
For you Fibber McGee and Molly fans there are 28 scripts there. Like "Quiet, Please"- there's 64 episodes of that show. However most shows on the site have only a couple of scripts for the series.
It looks like good repository for OTR scripts so I thought that I would share this with you.
