I really appreciate the way in which the British Library is constantly finding ways to preserve objects long beyond their format works. In this case, sounds that are rapidly deteriorating in their present form.
One of their other projects is to archives internet sites for posterity, anticipating a time when internet won't look anything like it does at present. One of these sites is my own Sabotage Reviews.
History is literally fading away in London right now. Many of the items in The British Library’s vast collection of recorded sound are in danger of disappearing. Some just physically won’t last much longer. Others are stored in long-dead formats. In the future, a hard drive full of photographs may serve as the digital analog of a pile of old pictures. But those sounds can be salvaged — for instance, the library has managed to save one of the few recordings of Florence Nightingale, which is preserved from an 1890 wax cylinder.
