WHERE DID THE WEB SITE ORIGINATE?
URLs (Web addresses) for Web pages outside the United States (and some Web sites within the U.S.) contain a two-letter code indicating the country where the Web page originates.
The Web site Domain Name Registries around the World can help you determine the country of origin for a particular Web page.
Examples: ca = Canada
de = Germany
fr = France
uk = United Kingdom
us = United States
The URL for the Canadian Library Association's homepage is http://www.cla.ca/
