A major part of the research process includes evaluating the sources of information you locate in your searches. In other words, this step includes searching for relevant information sources and deciding whether to keep and include those sources for your research or discard them in favor of newer, more reliable, higher quality sources.
When considering whether or not to use a source, ask yourself these questions:
WHO Who wrote the information? Do they have any professional experience or credentials? Is the website sponsored by a company or organization?
WHAT Does the information relate to your topic or address your research question? Who is the intended audience?
WHEN When was the information created, published, posted, or last updated? Is your topic particularly time sensitive?
WHERE Where did the information come from? Are there sources or links provided?
WHY Why was the information created? What was the goal of publishing this content for the world to see?
AND FINALLY...is this information better than what I could find in databases or other published literature? If the answer is no, keep searching!
