All websites will need to be checked for authority. Not all websites are curated by academic experts, some are copying-and-pasting from other sources (Wikipedia does this) and some are trying to sell you something by providing information first. The librarian has selected a few websites that you could use, but you will need to cite them on your own.
Despite the silly name for this acronym, the CRAAP test can help you determine if a website is useful or not. Use this as checklist for every website. And if you cannot determine something for a particular site, ask a friend or teacher for help.
