‘They’ve turned one of our most important pieces of national infrastructure into an internet café,’ was how my friend Marcus, a scholar of early modern literature, put it to me, talking about the cyberattack that crashed the British Library at the end of last year. He’s not wrong. Since October, when a ransomware attack by the Rhysida criminal gang knocked all the library’s digital services offline, there really hasn’t been much more to the library’s Euston headquarters than a large airy building with a couple of expensive coffee shops.
