Yes, Archive.org is a stand-by, and I thank you for the OTR Researchers link that we weren’t aware of. Excellent! I’m glad you’re writing a blog. That’s good stuff!
I’ve been doing it for quite some time, now. I took a few breaks now and then to try to think of better ways to do it, but I got back on the horse last week and don’t plan to hop off. Especially since I keep finding stuff I hadn’t fallen upon before even with 12,000+ shows in my collection already!
