Obituaries that appeared in print newspapers during the 20th century were easily disseminated and decentrally archived (typically by loved ones and libraries), making them relatively rot-tolerant.
Distribution isn’t a problem for digital obituaries, and in many ways the web is better than print in this respect.
But when it comes to preservation, there are many factors that make digital obits in their current state particularly susceptible to rot. They tend to be centrally archived and often behind paywalls, making them susceptible to digital rot and difficult for organizations acting in the public interest to archive.
The for-profit company Legacy.com controls a strikingly large share of the market for digital obituaries. It partners with funeral homes and newspapers, and in many cases when a visitor browses obituaries on the website of a local newspaper or funeral home, they’re actually redirected to Legacy.com, which hosts the content.
Unfortunately, the newspapers and funeral homes themselves often don’t maintain their own copies of the obituaries. What happens if Legacy.com or one of the smaller memorial sites goes out of business or experiences some sort of data loss? Because of the centralized nature of how these digital obituaries are stored, it’s possible that very few other organizations will have archived copies of the content.
