Friday Free Stuff: Historic maps
18 May 2012
The David Rumsey Map Collection has over 30,000 items (especially rare 18th and 19th century maps) available online under a Creative Commons Attribution Non-Commercial Share-Alike license. They can be searched and viewed through a variety of methods including the "LUNA browser" - as an example see their maps of New Zealand.
And for historic maps especially of Christchurch, see the Christchurch City Libraries collection digitised from several library and archival collections - you can browse either thumbnails or the title list to access these. Each map indicates its copyright status and usage rights.
