Beginning a search

If you are presented with a new term or concept, with the expectation that you'll inform yourself about it and investigate what's being done by active researchers, where should you start?

The answer depends in part upon what you already know, in part upon what resources you're already comfortable with, and in part upon what the outside world (in this case, your faculty supervisor) expects of you. A few years ago the obvious starting place would have been dictionaries and encyclopedias; for the last 4 years or so the 'electronic card catalog' [ANNIE at W&L] has been the first tool of choice; but now a persuasive argument can be made for starting with the World Wide Web --and if you're in Dr. Wielgus' group, that's your explicit assignment.
Whatever starting place you choose, your task is primarily linguistic in that you have to make sense of terminology as you read items (books, articles, references, etc.) you encounter. And it's certainly true that you'll need to explore a wide variety of possible sources. As I've noted elsewhere,

No single source contains everything you need;
every search teaches you something.

Consider what the various possibilities can get you:
