Vocabulary in English

I've been trying to find resources pertaining to the frequency of words in English - surely there must be some kind of graded scale of "commonness" or something? But so far I can't find anything that organized.

Instead, I've got two interesting links here:

• English for Academic Purposes
• 1000 most common SAT words

If we consider each of those and their ilk to be "general vocabulary words", then we'll have that much more luck in identifying technical content in a given document.
