«The OldMapsOnline Portal is an easy-to-use gateway to historical maps in libraries around the world.
It allows the user to search for online digital historical maps across numerous different collections via a geographical search. Search by typing a place-name or by clicking in the map window, and narrow by date. The search results provide a direct link to the map image on the website of the host institution.
Its creation was funded by JISC».
