Lots of news lately about the value of the dollar, the U.S. economy and so on. Want stats on the value of a dollar? The Federal Reserve has a web page with many links for detailed lists of the value of a dollar.
And of course there would be many excellent resources off the library web page in our Article/Databases section to find articles on the US economy. One excellent place would be Business Source Premier, or the Wall St. Journal, both available online in our Articles/Databases page.
