I am completely on the IA's side here, and I hope they win the case. Down with copyright. However, "on average, each recording in the collection is only accessed by one researcher per month" seems to me like a dishonest way to present the data. Surely surely there are one or a few recordings in the project that are vastly more popular than others. That's always how it goes. So "on average" completely obscures how pop…
Shouldn't the plaintiffs then single out that particular popular record, and not try to take down the entire catalogue? It goes both ways - if you ask for all you get data about all and that data shows one access/month.
Their approach stands on applying the law as written: "This is mine and you can't have it, even if I don't really much care about it."
