It's only really during the mass exodus of a fire alarm that the sheer scale of operations daily at the British Library become clear. Here's a picture I snapped of the readers flocking back into the building. Lucky this didn't happen yesterday during the Digital Researcher conference! It was also notable that, on re-admittance, there were no security checks. This, in my mind, seemingly defeats the point of the fact that I have to queue every morning to get in. Security is only ever as strong as its weakest point, be that a back door or a fire alarm.
