Information is essential for writing history of a time which can be gathered from various sources. Apart from official documents in the archives, historians gather information also from old newspapers, diaries of people, accounts of pilgrims, autobiographies of important personalities and booklets etc. Information found in newspapers is varied, based on incidents that have happened across the country whereas; the police reports are limited and localized. Because of this fact sometimes the information historians get from police reports is not as useful as it is from old newspapers. However for any incidence the newspaper may not quote all the reasons behind this and biased as per the thinking of reporter while in police records we could find some evidences for an incident and unbiased reports.

A police report may give a version which was suited to the rulers of that time. A newspaper may project a different story. Projection in newspaper depends on the leaning of the newspaper towards a particular powerful group in the contemporary period.
