The legit way - do a 'google scholar' search typing in the key word or phrase in your essay. If thats too much type in the whol question and google scholar will suggest relevant academic papers.

The suspect way - ask AI. Some uni's welcome the use of AI, others dont so check what your class teacher's position is on this. The Russell Group unis welcome the use of AI. Simply ask 'Claude' for references for your topic. It will generate references for you - many will be legit and many will be made up by the software e.g. "I have found one reference from Brown who has written about the culture of native tribes in Sudan so I will make up some other references quoting Brown that he could have written". That is how AI works, they join dots, sometimes in incoherent fashion. You could even ask AI to suggest an essay structure or a position for you to take in your essay. Again - all with the caveat that you are allowed to use AI.
