...check out this public policy research guide.

Many fantastic public policy resources--in particular, policy briefs from think tanks, NGOs, and research institutes--can be found online. Here are a few tips for more efficient, effective Google searches:

Include the phrase "policy brief" in your search. (Keep the quotation marks around "policy brief" to find this exact phrase.)

Use a site: search. This will limit your search to a broad domain (e.g., .org sites, .edu sites, .gov sites) or to a specific website (e.g., http://www.urban.org).

If you're not sure which think tank, NGO, or agency might have issued policy papers on your topic, try a search engine that's powered by Google but limited to a select group of sites.

• Think Tank Search (Harvard Kennedy School): A directory of U.S. and international think tanks, as well as a custom Google search of more than 250 think tank websites.
• Intergovernmental Organization Search Engine: Searches across hundreds of IGO websites.
• Non-governmental Organization Search Engine: Searches across over a thousand NGO websites.
