Suppose you have read two different books on world war ii in each book has different arguments about how the war started which of the following best describes the stronger historical argument?
a the argument that does not use any electronic sources
b the argument with the most reliable cited sources
c the argument that has the most sources
d the argument that was written most recently

The answer is B: the argument with the most reliable cited sources.

Historical research, like any other form of research, depends upon sources in order to make a verifiably argument. A reliable source, in a historical perspective, would be one that is founded on matter of facts, historical proofs and events that can be corroborated and verified through other research contributions or even further original research. For these reasons, a stronger historical argument would be one that is based on the most reliable cited sources.
