Our mission

Free Government Information (FGI) is a place for initiating dialogue and building consensus among the various players (libraries, government agencies, non-profit organizations, researchers, journalists, etc.) who have a stake in the preservation of and perpetual free access to government information. FGI promotes free government information through collaboration, education, advocacy and research.

Research data lost to the sands of time

Here’s an interesting article, not on link rot (a topic FGI has been tracking for some time), but on *data rot*. In a recent article in Current Biology, researchers examined the availability of data from 516 studies between 2 and 22 years old. They found the following:

  • that the odds of a data set being reported as extant fell by 17% per year;
  • Broken e-mails and obsolete storage devices were the main obstacles to data sharing
  • Policies mandating data archiving at publication are clearly needed

Librarians have known of this issue for years — the Inter-university Consortium for Political and Social Research (ICPSR) was set up in 1962 to tackle this — but it does put the issue in focus. And finally the federal government — via efforts like the NSF’s data management plan and OSTP’s new directive to improve the management of and access to scientific collections — is beginning to get behind the effort to improve on data rot. And many libraries — not to mention scientists and researchers — are beginning to struggle with the issue of data preservation. The issue is too big for just government information librarians to handle obviously. But this is fertile space in which govt information librarians, data librarians, research communities, and federal agencies can come together. The Federal policy stating the importance of data preservation is there, it’ll just take effort by multiple stakeholders to make sure it actually happens. It’s a positive that the writers of Dragonfly, the blog of the National Network of Libraries of Medicine Pacific Northwest Region — where I came across the article — point out that academic institutions can and should play a leading role in data preservation. I wholeheartedly agree!

The researchers found that for every year that had passed since the paper’s publication date, the odds of finding an email address that led to contact with a study author decreased by 7% and that the odds of turning up the data reduced by 17% per year.  The authors report that while some of the data sets were truly lost others fell more into the category of “unavailable,” since they existed, but solely on inaccessible media (think Jaz disk).  These findings will not come as a shock to those who have worked in a research lab.  This publication does put some tangible numbers behind the underlying message of NYU Health Sciences Library’s excellent dramatic portrayal of an instance of inaccessible data.  The authors conclude by suggesting that a solution to this problem moving forward can be found in more journals requiring the deposit of data into a public archive upon publication.  I would also suggest that academic institutions can take a role by establishing policies supporting research data preservation alongside providing a data repository.
