CRAAP Test by librarian Sarah Blakelee (2004), CSU Chico. 

The process of evaluating a source includes examining the source itself and examining other sources.

Use the CRAAP Test to help you determine if the sources you found are accurate and reliable. Keep in mind that the following list is not static or complete. Different criteria will be more or less important depending on your situation or need.

Run a Search in Google

It also might be a good idea to browse the websites and blogs of science magazines. Keep in mind, for magazine websites, you might not be able to access all of the content. (The databases will provide you with access to content behind paywalls, but the library can't subscribe to everything.)
