This is a really helpful guide put together by JSTOR librarians and aims to help you learn the basics in research skills. This will help you get the best from searching including how to control the amount of information you get and how to check that your information is credible. There are three modules to go through each ending with a practice quiz. https://guides-jstor-org.nls.idm.oclc.org/researchbasics
It's really important that you evaluate the information you have gathered so that you get the best possible marks for your piece of work. The web is full of misinformation, disinformation and fake news so in order to check the credibility of the source you can apply the CRAAP test. The test is a tool to help you check the resources you have found. It was designed by Sarah Blakeslee, a Librarian at the Meriam Library California State Universiy, Chico and is widely used in further and higher education.
