Patrick - Thanks!

That's a solid index and practical introduction. I have a bookmark for the website, but not that page. ALthough it's designed for community college students, many of my university students - both ESL and non-ESL - have found it quite helpful.
Again, good tip.

By the way, I also share your appreciation for Wikipedia - and even allow students to consult it as a first source for research papers. They have to, of course, find the same information elsewhere - and remain sceptical of all sources. After all, even the most "respected" and "reliable" sources have often been very wrong.
