A scan of archives shows that lots of scientific papers aren't backed up.

Back when scientific publications came in paper form, libraries played a key role in ensuring that knowledge didn't disappear. Copies went out to so many libraries that any failure—a publisher going bankrupt, a library getting closed—wouldn't put us at risk of losing information. But, as with anything else, scientific content has gone digital, which has changed what's involved with preservation.

Organizations have devised systems that should provide options for preserving digital material. But, according to a recently published survey, lots of digital documents aren't consistently showing up in the archives that are meant to preserve it. And that puts us at risk of losing academic research—including science paid for with taxpayer money. //

The risk here is that, ultimately, we may lose access to some academic research. As Eve phrases it, knowledge gets expanded because we're able to build upon a foundation of facts that we can trace back through a chain of references. If we start losing those links, then the foundation gets shakier. Archiving comes with its own set of challenges: It costs money, it has to be organized, consistent means of accessing the archived material need to be established, and so on.

But, to an extent, we're failing at the first step. "An important point to make," Eve writes, "is that there is no consensus over who should be responsible for archiving scholarship in the digital age."

A somewhat related issue is ensuring that people can find the archived material—the issue that DOIs were designed to solve.
