a while ago, like in the '60s or '70s, a librarian did a research project on librarians' commitment to intellectual freedom: he dressed up like a hippie, then went to various libraries and asked for information on the quantities of explosives needed to blow up a house. In the '80s, another researcher performed a similar study: he put on sunglasses, then asked librarians for information on how to freebase cocaine. i could be repeating these studies. but instead, i'm writing a survey about open-source software. i am really not very bright.
