The race is on to save the millions of web pages that disappear from the net every day.
Concerned that the huge amount of data and information, which is of historical significance, could be lost, the British Library is is having a crack at saving it.
The library, which has been saving books for more than 200 years, is running a pilot project that will archive some 100 British websites. Once it is up and running it plans to save more than 10,000 sites in a scheme called Domain UK.
Sites being selected are of social and historical importance to the UK and require the library to get copyright clearance to make its archive available to the public.
This is because the archiving of material has changed dramatically since the development of the computer.
Previously book, magazine, periodical and newspaper publishers sent copies of everything they produced to the British Library, which filed them away.
Digital information does not have the same obligation, meaning that much electronic information is lost forever.
The British Library estimates that thousands of web pages and sites, which one day could be seen as invaluable documents of our time, are disappearing.
For example some of the pages that people put up to commemorate the death of Diana, Princess of Wales, or the loss of friends in the 11 September attacks, have all but disappeared from the web.
As well as regularly archiving 10,000 sites, the library will take a look at, and store some of, the .uk domains which currently run to about 25 million pages.
