The British Library is to 'harvest' billions of web pages, blogs and e-books in a bid to preserve and document the nation's 'digital memory'. For centuries, the library has kept a copy of every book, pamphlet, magazine and newspaper published in Britain. It will also be bound by new regulations to harvest the entire UK web domain to document current events and record the country's burgeoning collection of online cultural and intellectual works. The British Library, which has invested £3million in the project during the past two years, plans to collect the material by conducting an annual trawl of the UK web domain - every website ending with '.uk'. It will harvest information from another 200 sites - such as online newspapers or journals - on a more regular basis, as often as once a day. There's more on the British Library website. What do you think? Is it a great idea to document modern day life in this way?
