“One should not over-romanticise,” says the Guardian editorial marking the 225th anniversary of the Ordnance Survey’s first publication, even while doing so. I’m always a bit nonplussed by celebrations of paper maps; I think I’d feel better if they weren’t quite so antiquarian (this one uses words like charm, tactile and nostalgia). It is possible to make a functional argument for paper maps. (And in any event, the Ordnance Survey isn’t just about Landrangers any more; their maps and data have been available digitally for ages.)
