"You can join the latest phase of our project, which features over 50,000 more maps from the British Library collections. Help us identify accurate locations for these historic maps! Bear in mind that some places have changed significantly or disappeared completely, creating a puzzle that reveals an exciting contrast.
Your name will be credited, and your efforts will significantly improve public access to these collections. Contributors can see the results of their work, as well as the progress of the pilot and other participants, and the top contributor will be publicly announced."
