A second thing that Swanstrom takes into account in his definition of history is that historical events are not things that happen on a regular basis such as daily or weekly, etc. So this aspect of a historical event would then be stated as something that is generally unrepeated. There is one other part of the definition of history and that is the fact that history itself cannot be studied. To actually study history, a person would need to be able to travel back to the time of the event. Since this is not possible in this life, then all we can do to uncover as close as we can what actually happened is to study the records from that time in history.
History is a study of past records of significant and generally unrepeated events. .
The job of a historian is many. They must first define what period of history they are going to study. Once they have found the information covering that period in time, their next step would be of assimilating that information and then formulating it into as complete, accurate and unbiased form that they can. . A couple of questions may arise from my last statement when I use the words complete and unbiased. The answer to this would be that you would not know unless you took the time and effort to study the subject yourself.
