And just how is it that NOAO has any copyrights anyway? That's a publicly funded institution. Why aren't their products public domain from the start? For that matter, why is it that we pay for scientists to conduct research, and then we don't have free access to the journals? I understand that the journals are private enterprises, and they have to pay editors, printers, etc. But when they're charging $30 or more for electronic access to single articles, that's just ridiculous. Granted, they get to say that the articles are publicly available. But at $30, they're not selling any of those. Professionals get colleagues to snag the articles for them, and students go to the library. And it's just enough inconvenience to the independent investigators that it keeps them out. Argh.
