Google is an excellent tool for discovering primary documents from the U.S. government and think tanks, as well as international organizations, and foreign governments.
|Searching Google Effectively||The trick to searching Google effectively is to determine the Internet domain you wish to search, and then to perform a focused search using the "site" limit.
Here are some sample searches.
1. To find documents from a Think Tank you would use their top-level Internet domain. Then you would create the Google search using the "site" function:
gun control site:brookings.edu
gun control site:cato.org
2. The various U.S. government agencies can be searched the same way:
"gun control" site:house.gov (to find information about this topic from the U.S. House of Representatives)
"gun control" site:senate.gov (to find information about this topic from the U.S. Senate)
3. If you are trying to find policies from other countries, you can use their top-level Internet domains. You can discover these at the Domain Name Registries Around the World.
