The licenses above travel with the material. If you reuse something you found here, those terms apply to you the same way they apply to us — most often that just means crediting the institution that made it available. Every map page names the archive its map came from.
If we've miscredited a source, or missed an acknowledgement we owe, tell us and we'll put it right.
