Good Deed of the Day: Help Geo-Reference the British Library's Map Collection
Everyone wins, except your employer.
The British Library needs your help.
It is in the process of turning its gargantuan collection of maps into a digital resource tied to Google Earth. This allows people to see ancient and modern maps at the same time, with a slider to fade between the centuries. It's easy to compare a city to its younger self, or observe the geographic impact of dams, bulkheads, and embankments. You can spot the mistakes -- or marvel at the accuracy -- of mapmakers working in the pre-electric age.
