A feature that sounded obviously good

When I introduced Book Corners , I explained that much of its initial data came from OpenStreetMap . OSM gave the project a useful starting point, with thousands of public bookcases already mapped around the world.

Book Corners also accepts new libraries directly from its users. People can submit a location and a photo, and the contribution becomes public after moderation. It seemed only fair that, when one of those submissions was missing from OSM, Book Corners should be able to contribute it back.

The idea was not to create an uncontrolled background synchronisation process.…
