Once you've been done some research, you'll need to make sure that the resources you have found are credible. How do you go about this? For academic articles, see this page, and for popular/news materials, visit this page. Both pages are intended to give you the tools that you need to determine the validity of a material for your assignment.
When you evaluate information, you need to do it a little differently depending on the type of resource you're looking at, but how do you know the difference between an academic resource and a popular resource.
Determining the credibility of a resource can be exceptionally difficult in some cases. The nature of information in today's information landscape actually serves to help the spread of mis- and disinformation. Because information is spread so quickly through social media, information that is blatantly untrue can be seen to be true.
Combating this is really difficult, so if you would like assistance in this, please feel free to reach out to a librarian. We are trained to determine the validity of a claim, so if you aren't sure, we're here to help!
