What did we do? We programmed a Python script (very badly programmed, I am looking at you… the line with an “insert” query without binding variables!) that searches the Mendeley catalogue and inserts documents geo-located into a table in CartoDB. Then using CartoDB we displayed this data. And to make it more fun we displayed the data on a map with The Martian’s book trip. You can see that the specific locations featured in the story have many documents, partially because Pathfinder and Mars Rover were nearby.
