$100 Million Worth of Copyright Liberation?

My friend Andrew recently forwarded me this message from Wikipedia founder Jimmy Wales:
Imagine there existed a budget of $100 million to purchase copyrights to be made available under a free license. What would you like to see purchased and released under a free license?
Photos libraries? Textbooks? Newspaper archives? Be bold, be specific, be general, brainstorm, have fun with it.
I was recently asked this question by someone who is potentially in a position to make this happen, and he wanted to know what we need, what we dream of, that we can’t accomplish on our own, or that we would expect to take a long time to accomplish on our own.
It’s an interesting thought experiment, though I prefer liberating works from copyright abuse in a more unconventional manner, and would rather see funds invested in such causes. E-mail Jimmy with your thoughts, and maybe – just maybe – something will come of it.
