Information about the past is compiled, stored, and made accessible in a variety of ways. One of these ways is historical maps. Historical maps provide a chronology of important events and show the impact these events had on the places where they occured. Historical maps support and extend information from primary historical resources such as letters, treaties, and census data. Historical maps are summaries of past events presented in graphic form.
Blackline maps are often blank historical maps which allow you to record important details, aiding the cementing of knowledge in visual form.
