The British Library recently started a crowd-sourced mapping project. Pin-a-Tale is a map of places that have influenced British literature over the last 1,000 years. The pins on the map contain images and short stories about how places in the British Isles have influenced writing.
Applications for Education
Pin-a-Tale could be a good resource for lessons in British literature. Beyond that it is a nice model for a Google Maps project that your students could do for any other genre of literature. Teachers of American Literature might have students map the places that have influenced famous works in American Literature.
