Relief for Gas Prices (Information)

With gasoline at or above $4.00/gal in many Alaskan communities, there is growing interest in the forces and news behind rising gas patrons. While a library can't cut the price of unleaded, the University of Michigan has posted a new resource on gas prices at http://www.lib.umich.edu/govdocs/dn08/dn08gas.html. It can answer questions like:

How much does crude oil contribute to the cost of a gallon of gas?
How much taxes are paid on gasoline?
Where does gasoline come from anyway?
What are people across the nation paying for gas?

So stop in and fill 'er up with gas facts.

What sorts of subjects are your patrons asking you about? If you're having trouble finding resources in a given area, let me know and maybe I can find enough to do a post about it.
