Book covers looked very different a decade ago when the appearance of e-readers seemed to flummox a publishing industry reeling from the financial crisis and Amazon’s rampant colonisation of the market. Publishers responded to the threat of digitisation by making physical books that were as grey and forgettable as ebooks. It was an era of flimsy paperbacks and Photoshop covers, the publishers’ lack of confidence manifest in the shonkiness of the objects they were producing. But after reaching a peak in 2014, sales of e-readers and ebooks have slowed and hardback sales have surged. The latest figures from the Publishing Association showed ebook sales falling 17% in 2016, with an 8% rise in their physical counterparts. At the same time, publishers’ production values have soared and bookshops have begun to fill up with books with covers of jewel-like beauty, often with gorgeously textured pages. As the great American cover designer Peter Mendelsund put it to me, books have “more cloth, more foil, more embossing, page staining, sewn bindings, deckled edges”.
