What needs referencing
Before considering what needs to be referenced, it may be helpful to first consider what does not.
'Common knowledge' is the term used to describe established facts that are not attributable to a particular person or authority. For example, it is known that John Lennon was assassinated in 1980, in New York, by Mark Chapman. However, what is less likely to be classed as common knowledge and therefore taken for granted is the exact reason why Chapman killed him. This is because there have been numerous theories, each one claiming to hold the answer.
