Dan,
Not sure if this has interest to you as a Ruth Fan...but I have a pretty extensive scrapbook collection from Ruth. It's almost entirely period newsclippings (mostly from newspapers) about him and his career. If I recall correctly its around 100 pages chock full of stuff from various parts of his career and afterwards.
Haven't really given much thought to selling it but would be open to do so. Shoot me an email if interested....
