As explained in this article from my hometown newspaper, the American Radio Archives and Museum is a "a still-growing collection [of radio broadcasts] that began in 1984 and now boasts some 30,000 audio recordings, 40,000 scripts and 150,000 photographs." It's especially focused on the "Golden Age" of radio from the 30s and 40s, before television became dominant, and is "one of the largest radio broadcasting collections in the world."
The organization is constructing a new museum to make more of their collection available to the public. This is a classic museum organizing system to a T. The most amazing part of the article (and seemingly the organizations mission) is there is absolutely no mention of the internet or the web. None at all. As far as I can tell, there are absolutely no plans to digitize the collection and make it available online. I am equally as amazed as saddened by this.
The likely reasons are a lack of time, money, and technical know-how. It is a perfect example of why a service that can alleviate these issues, such as
Pop Up Archive (a MIMS 2012 Final Project that's still being developed), is so sorely needed.
