One of the best resources you can use is Purdue University's OWL website. Here you can find out how to create citations for all types of materials (books, articles, websites) and see example pages so you can double check your works. Visit the site here: https://owl.english.purdue.edu/owl/resource/747/01/
You can also use citation generators like EasyBib, Zotero, or a browser extension like Cite this for Me. These are not always reliable, however, so be sure to check your work!
