Whether in academic or professional life, we need to find credible sources and base our arguments on valid evidence. When you are evaluating a source, look for clues by considering the Who, What, When, Where and Why of the source.
Authority - Who wrote/published it? Is the author qualified to write on the topic? What are their credentials? Is the publisher an academic institution, or a scholarly or professional organization?
Content - What is it about? Is it relevant and accurate? Does the information relate to your topic or answer your research question? Who is the intended audience? Is the language geared toward those with knowledge of a specific discipline rather than the general public? Does the author back up their claims with evidence or opinion? It’s ok to use sources that state opinion as long as you acknowledge it in your own work.
Timeliness - When was it published? How current are the citations in the bibliography? How current does the information need to be for your topic or assignment?
Source - Where did you find it? Was it in a library database or Google Scholar? If it’s from a website, what is the domain? If a commercial website, who is running it and why?
Purpose - Why was it written (e.g. to inform, teach, entertain, persuade)? Are there any obvious biases?

You may want to do some preliminary research to refine this topic and possibly find something more specific to search for such as:
To search phrases or titles with multiple words, use quotation marks. Putting these terms in quotes means that the words will be searched as a phrase rather than each word separately. For example:
Combine keywords using the AND operator to narrow your topic. For example:
Combine keywords with synonyms using OR to broaden your search. For example:
