OK. Here it is. I finally finalized (sort of, kind of, maybe) that resource ranking chart I mentioned last week. I'm posting it via Google documents. You can find it here in PDF. You can download or print the document from there. It might be a useful tool when dealing with resource selection in information literacy courses or in any course requiring research.
I would really like some feedback on this since I know I have at least one librarian reading this (I'm looking at you C). I waffled between four and five ranking sections before finally settling on four. However, there's lots of room for flexibility and movement in this chart. The rankings can break down by decimal if necessary.
Making a general chart for this sort of thing is more difficult than I originally thought. I think modifying the chart to be subject specific would take away some of the ambiguity. However, any little bit of guidance I can create to help students or other curious people is still a good day's work in my book. Unless, I've managed to confuse them more.
EDIT: I'm posting a comment from C below. She was able to email me the comment, but couldn't get anything to post in the comment section.
