LitHub: “…It’s called a “slow fire,” this continuous acidification and subsequent embrittlement of paper that was created with the seeds of its own ruin in its very fibers. In a 1987 documentary on the subject, the deputy Librarian of Congress William Welsh takes an embrittled, acid-burned book and begins tearing pages out by the handful, crumbling them into shards with an ease reminiscent of stepping on a dried-up insect carcass.
The destruction is inevitable. Depending on how a book was made and how it’s been stored, embrittlement can happen in as little as 30 to 100 years. Already, books have been lost, and the methods of preservation are too limited, time-consuming, and expensive to address the scale of the problem. Mass deacidification, where an alkaline neutralizing agent is introduced via a spray or solution applied to paper, once seemed like the golden solution; but while it can be used to prevent slightly acidified paper from deteriorating, it doesn’t reverse the effects of prior damage. The fallback is digitization—a fancy way to say mass-scanning, and the most used method of saving the content of a text, but not the book itself. In an article about the Library of Congress’ digitization efforts, Kyle Chayka reports that it would take literally decades of scanning to preserve the institution’s over 160 million object collection. At our existing technology’s current scanning pace, preserving the prints and photographs division alone would take about 300 years…”
