Sometimes it's difficult to locate the statistic you want on a website. Google can help.
Just type your search term in the Google search box ("unemployment rate," for example) then type site: and the address of the website you're searching (for example, "unemployment rate site:www.bls.gov").
Google will search only that site for your search term, helping you locate the numbers you need. And if you're not sure of which site to search, you can search on just a domain, site:gov for example.
Google Books searches thousands of scanned books. Use the find in a library tab to the right of the book title to discover which library has a print copy of a specific individual book.
