Maps and Books have always interested me, independently from each other. I recently spent a fair bit of time exploring their intersection, via my website CodexMap, which is a Google Maps / Amazon Books / LibraryThing / Geocoding mashup, letting you interactively explore a Google Map to find & place books.

Imagine my delight at finding someone taking this intersection to the next level. Literature in a map, not on a map. Via Bruce Sterling’s blog on Wired, and Entropist, I found “The 21 Steps” – a creation of Charles Cumming, the author of “Typhoon“. It’s a story (a takeoff of “The 39 Steps“), told via an interactive Google Map. It’s Great Fun. Check it out.
