To cite and reference:
1) Check which style is required by your assignment and look up the rules for this style. Review what bits of information are needed to create references in your style, e.g., author, publisher, journal title, etc.
2) Keep careful notes of your reading, and gather all the bits of information your will need to create a reference. (Reference Management Software like EndNote can assist with storing information about your reading.)
3) When you use information from your reading, insert a citation to show your source.
4) Create a reference for your source, and add this reference to your list.
You must read the items you are referencing, and make sure they back up your claims.
(Do not use GenAI tools like ChatGPT to create a reference list for your assignment - the suggested items are unlikely to be relevant, and are often hallucinated by the AI.)
