TAR: research hierarchy or progression

["Ruffin L. Priest" <rpriest@CHCCS.K12.NC.US>]

I am looking for a research progression or hierarchy. I heard about it in library 
school, but can't find my notes!

It was set out as a list of steps to investigate a problem and says something like:
Encyclopedias first (because they have a broad or overview range of information)
Books, then articles. Internet was last. I seem to remember that there were six 
levels.

Thanks so much for your help!
Ruffin
