I read this article recently : “Why do we ask the same questions? The triple helix dilemma revisited,” by Richard Delgado and Jean Stefancic, 99 Law Library Journal 307 (2007). (This whole issue of 99 LLJ is terrific, especially for legal research geeks.)
The article reminded me of a lesson I teach legal research students, but explains the whys and wherefores better than I ever could. In essence, the lesson is, don’t let legal publishers, or anyone else for that matter, do your research for you.
This is a liberating position to take. No longer do you just have to plod through the digests, the reporters, etc. You now have permission to read history, philosophy, literature, science fiction, and anything else you may want. Answers to questions, past and future, will be found if you read widely.
