Andi suggests “Writing a literature review involves finding a published paper on the topic and writing a summary of it.” 

Caris claims “You need to read several recent articles on the topic, think about what they are discussing, and then summarise your ideas, with references to the original sources.”

Dava says “You need to quote at least one sentence from each article you read about the topic, then add your own interpretation in the conclusion.”

Bobby proposes “A literature review is a summary of the main articles on a particular topic, without adding anything new.”
