Opera and musical comedy search
I think this is definitely one of those posts where some of you will say, "Wow, that's really cool" while others will say, "Why in the heck would I be interested in that?"
Someone, for whatever reason, has compiled a list of all (well most of) the operas and musical comedies produced for television during the last half century. The site was created along with the Indiana University Digital Library Program. You pretty much have to have some knowledge of opera or musicals in order to use it, otherwise you won't know what to search for. As I said, it's probably not everyone's cup of tea, but I had fun poking around the site. Besides, now I know that Carol Burnett played Calamity Jane in 1963. That kind of information will have to come in handy sometime.
