Photographs, audio recordings, and video recordings document what happened at a particular time.                                                                                              

Photos can be old family photos, photos of prominent historical figures, sports figures, architecture, landscapes, or a particularly good line of Boston Terriers.  Depending on what topic you are researching, they can be photos of anything.

Video can also be used as a primary source.  Video of an event, interviews, and documentaries are all useful and quite palpable methods of conveying information.

Additionally, audio recordings of events, such as 911 calls and interviews are useful primary sources.
