The British Library has just launched the UK Web Archive, which has been in development since 2004. Here you can see how sites have changed over time, locate information no longer available on the live Web and observe the unfolding history of a spectrum of UK activities represented online. Sites that no longer exist elsewhere are found here and those yet to be archived can be saved for the future by nominating them. The Archive contains sites that reflect the rich diversity of lives and interests throughout the UK. Search is by Title of Website, Full Text or URL, or browse by Subject, Special Collection or Alphabetical List.
