Citing your sources is important as it shows you have the right background knowledge on the topic. It also provides credit for ideas that are not your own. Citing allows your reader to follow up on an idea that they may have discovered from your writing.
You may want to use a citation generator to help create your citations. Most databases, as well as Google Scholar, provide quick copy-paste citations for users. You should use these copy-paste citations as a draft and ensure you review them for any errors based on the advice from the citation style guides linked here. Many of these automatic generated citations will have errors.
