Old maps online: historical map archives to explore

Historical maps used to live in reading rooms. Now the biggest collections are online, in high resolution and free to browse — and some of them let you slide through time over the same place.

These are the archives we picked for foundaday. Start with the David Rumsey collection if you want sheer size; pick a time-slider map if you want to see one country change.
