WRS is a search engine that is limited to a few hundred higher-quality sources. Examples include nytimes.com or ieee.org for example. As with any search engine, editors must still exercise their own judgment to ensure any specific reference meets the reliability requirements for the intended use. So next time you want to work on an article, you can easily study reliable sources and possibly identify ways to improve the article text based on your search!
WRS can make a reference search very efficient, but it is not a substitute for critical analysis. We are working hard to make sure WRS shows only reliable pages, but search results always contain some irrelevant or unreliable pages. Please identify within the results which page is the best reference for your fact. Not every search result will be a reliable reference in the article you are editing.
