When I was in law school, I was a teaching assistant for an environmental law professor. One of the tasks he had me working upon was a review and analysis of electronic databases that could be used to assess natural resource damages when some environment harm took place, such as the Exxon Valdez oil spill.
How do you determine the cost of the spill to the environment, to wildlife, to people who live in the area, to people who rely upon the area for their jobs and welfare. In short, you look at things such as other decisions in other courts where such things may have been litigated.
At the time, the World Wide Web was still a year away, and many of these electronic databases we were looking at were very helpful sources of information. My task was to review those, and see how much value and help they might hold.
