World history resources rely on data like numbers and names for in depth research. Here’s an example of how this works. Say you want to know what kind of car your favorite serial killer was driving so that your crime novel can be more accurate. You know your character got a tow truck service on the day of his most famous crime so you go to the company’s office that towed him and look through the records to see which car your character was driving. This story illustrates just one reason why tow trucks and fancy cars are helpful for world history. The records car owners and towing businesses leave behind can be used in fascinating and unexpected ways.
So if you’re reading this and you keep records, make sure you do keep them because hundreds of years from now those records might be used by a historian!
