The British Library welcomes participation in this effort to "place" its treasures of historic mapping. The outcomes greatly enhance knowledge and access to these maps in a new and engaging way, and enable them to be reused and developed in future.

The British Library is grateful to all participants; their work expands knowledge of and access to these maps tremendously, and produces results not otherwise possible. This page tracks individual participant’s contributions.

To view the maps that have already been placed, see Maps already georeferenced.
