Increased computing power and disk space combined with decreasing costs were supposed to make anything born digital possible to store for ever. But digital data often has a surprisingly short life. The most obvious problems for digital archivists have to do with hardware, but they are also the easiest to fix. Many archives replace their data-storage systems every three to five years to guard against obsolescence and decay. This is not as expensive as it sounds: hard drives are cheap and reliable. The threat of hardware failure is overcome by keeping copies in different places. The British Library has storage sites in London, Yorkshire, Wales and Scotland. Collecting digital material is trickier, particularly online. Archivists can only harvest those parts of the web that are freely accessible. Anything requiring user inputs--passwords, searches, forms--is off-limits. Streaming media, such as online videos, are hard to capture.
