In the last couple of months the BBC has been celebrating the success of 20 years of BBC Online. Many have asked how BBC Online has been archived over the years. The good news is that it’s been archived comprehensively, through a number of different approaches.
The key has been in working with institutions like The British Library's UK Web Archive and The National Archives's Online Web Archive, through sharing knowledge and ensuring consistency in standards, particularly around the international web archive standard WARC. This improves the ability to share online resources with each other in the future. This has led the BBC to adopt a more focused and widely accepted method of web archiving called crawling.
