Primary sources are records of events as they are first described without any interpretation or commentary. An example would be Samuel Pepys diary account of the Great Fire of London in 1666. Letters, memoirs, census data, newspaper articles of the day, are all examples of Primary Sources materials. These accounts can be written, oral, visual, or electronic transmission.
