Factors like language, culture, access, finance, boarder, technology, etc. effect the selection of data sources. With the passage of time, choice of data collection sources changes. In this paper we studied, compared and contrasted the different sources used by the historians to record the historical events. We also studied the impact of different sources with regard to authenticity and availability. We opt for political history of last one hundred years of Indian Subcontinent as our case study.
