5.2 : When am I not required to reference my information sources?

There are situations where you do not have to refer:

Well-known fact: the start and end date of World War I (1914-1918); the name of the current chancellor of Germany (Olaf Scholz).

A lesser-known fact: the start and end date of the Third Punic War (149-146 BC); the name of the Madagascar Senate president who served in between 2008-2009 (Yvan Randriasandratriniony).

Tip! When in doubt, use a source citation.
