There doesn't seem to be an appropriate category for this, so I'll post it here. I am looking to amass information about all films that were released to super 8mm from the 60's -90's by Castle (Universal), Columbia, Disney, Mountain (Paramount), AAP (Warner), Ken (Fox and AIP), Derann, etc. in order to produce a book on the subject of 8mm film collecting. Has anyone information about where listings from catalogs from these companies can be found? Any help would be greatly appreciated!
