When writing an essay or posting an authoritative article to your website, you want to rely on credible sources. A credible source is one whose authorship and information can be vetted. That is, the ideas are the writer's own ideas and there's substantial evidence in support of their statements.
If you're looking for a credible source to bolster your own work, you'll only want the best. A non-credible source will give you no indication where they got their information, will be poorly written, and will make your tail curl if you suspect it may even be plagiarized.
How to find credible sources? Begin at your school's library and extend into the vast web. After we discuss those two elements, you'll find a formula to help you tell if a source is credible.
