Use Google’s advanced searches to limit your results to more reliable domains (e.g. .gov and .edu).
To help you evaluate the sites you find:
related: search for related sites, use the word "related" followed by a colon: related:api.org
link: Find out where someone referenced this link on the website: link:wwf.org
v-e-r-y important: there is no space after the colon when using these commands; don't need to put in the "http" or the "www"
