Going to the Sources - Chapter 1

In Chapter 1 of Going to the Sources, Brundage explains to the reader that history is not a passive discipline.  The problem, he says, is that history has been presented as a story with a fixed plot and cast of characters.  Brundage goes on to explain that history is a dynamic process.  Brundage explains that different historians or groups of historians present different views of the past. 

For example, Revisionism is when an historian challenges an established way of interpreting the past.  It suggests that as society changes, so too should our views of the past.  Brundage explains how historians such as John Richard Green have changed the focus of history and turned the spotlight oaway from the elities and towards everyday people.  In addition, the history of women and minorities are new areas of study.  The Annales School focuses on social studies, and Cliometrics requires quantifiable data.  Psychohistorians search for feelings as well as facts.  Microhistory, macrohistory and postmodernism are all new and different ways of approaching history.

Under the idea of Revisionism, does it mean that we should change history to suit our modern views?  And what would happen to the "old" history?  Does it become history?

Question 2
How can you tell which style of history an historian is using?
