We're losing our digital history. Can the Internet Archive save it?

Research shows 25% of web pages posted between 2013 and 2023 have vanished. A few organisations are racing to save the echoes of the web, but new risks threaten their very existence.

It's possible, thanks to surviving fragments of papyrus, mosaics and wax tablets, to learn what Pompeiians ate for breakfast 2,000 years ago. Understand enough Medieval Latin, and you can learn how many livestock were reared at farms in Northumberland in 11th Century England – thanks to the Domesday Book, the oldest document held in the UK National Archives. Through letters and novels, the social lives of the Victorian era – and who they loved and hated – come into view.

But historians of the future may struggle to understand fully how we lived our lives in the early 21st Century. That's because of a potentially history-deleting combination of how we live our lives digitally – and a paucity of official efforts to archive the world's information as it's produced these days.

However, an informal group of organisations are pushing back against the forces of digital entropy – many of them operated by volunteers with little institutional support. None is more synonymous with the fight to save the web than the Internet Archive, an American non-profit based in San Francisco, started in 1996 as a passion project by internet pioneer Brewster Kahl. The organisation has embarked what may be the most ambitious digital archiving project of all time, gathering 866 billion web pages, 44 million books, 10.6 million videos of films and television programmes and more. Housed in a handful of data centres scattered across the world, the collections of the Internet Archive and a few similar groups are the only things standing in the way of digital oblivion.
