A paper record in a decent box is readable in a century. A digital record can become unreadable in a decade — not because the bits were lost, but because the format is obsolete, the software is gone, or the media has failed. Keeping records usable over time is the goal of digital continuity.
How obsolescence happens
- Format obsolescence — a file format is no longer supported by current software (think of proprietary formats from defunct applications).
- Software/hardware dependence — a record needs a specific (now unavailable) program or system to render correctly.
- Media decay — hard drives, tapes, and optical discs degrade and fail over years.
- Loss of context — without metadata, even a readable file becomes uninterpretable.
Digital continuity
Digital continuity means ensuring records remain complete, available, and usable for as long as they’re needed — which for permanent records can be indefinitely. It’s about managing the dependency between a record and the technology required to use it, so that changing technology doesn’t silently strand your records.
How to prevent it
- Choose sustainable formats. Favor open, widely supported formats for records, especially those with long retention. The Library of Congress publishes guidance on format sustainability.
- Migrate proactively. Periodically convert records to current formats before the old ones become unsupported.
- Check fixity. Use checksums to detect corruption over time (see digital preservation).
- Keep metadata with the records, so they stay identifiable and interpretable.
- Plan for system migrations. When you retire a system, plan how its records move forward — a frequent point where records are lost.
Why it matters
Format obsolescence is a slow, silent risk: nothing looks wrong until you try to open a record and can’t. For records with long or permanent retention, digital continuity is essential — it’s the difference between a record you can still produce as evidence years from now and a file no one can open. It connects everyday electronic records management to long-term digital preservation.
