So tonight I find myself in the computer lab, looking for information for a research paper due Wednesday. It's for my Legal Issues in New Media class, and the topic I've chosen to tackle is copyright terms. Right now I'm working with the juxtaposition of increasing copyright terms and what I'm calling the decreasing shelf life of information. The copyright term aspect is pretty broad and straight-forward, but the fun part is trying to figure out how you reasearch the latter aspect. What metric do you use to determine how long information is useful?
