Records are the most common type of content on the map. These can be stories, events, images, videos – text – anything, really. Every black pin on the map represents one record, and every white circle with a number in the centre represents the number of records shown in the centre.

Examples:

• #RememberHer Sylvia Pankhurst (1882-1960) on Layers of London
• Huntriss Row on Scarborough Atlas

Collections are made from groups of records with a common theme. They don’t have pins on the map, but the records they are made of do.

Examples:

• A Medieval City on Coventry Atlas
• Albert Dock on Mapping Memory

Overlays are either historical maps or data that lies on top of the base map.

Examples:

• World Map, 1900 on the Refugee Map
• Charles Booth’s Poverty Map on Layers of London

Trails are walkable series of records that you can explore online or in person. Their pins are green with an illustration of a map pin with a route.

Examples:

• Scarborough Old Town on Scarborough Atlas
• Radical Clerkenwell Trail on Layers of London

Journeys tell stories of people/items that travelled great distances, like an ocean voyage.

Examples:

• Wilhelm Pollak’s journey to safety on the Refugee Map

Timelines can be used to tell stories over periods of time, like decades or centuries.
