Sources of Information
The sources of information can be classified and put into three different categories: Primary, Secondary & Tertiary. This classification is based on the originality of the material. Talking about a historian needs to record information; multiple sources of information will be needed for him to have a broad and clear picture. Various sources of information include newspapers, public accounts, official documents, and police records.
Information provided in the newspapers was majorly based on the real-time reporting of facts and mainly on what people of the country felt and thought about any particular incident or issue.
On the other hand, police records are official and backed up by official documents. Though official, these records may be biased. They basically communicate the officials' side of the story as they deem fit and correct. Also, police records may be biased based on the opinions of those in power.
