A registry holds four decades of files. They are complete, they are the legal record, and they are degrading. The proposal on the table is to scan them. Scanning is the easy part.
What makes an archive usable
A scanned page that cannot be found is no better than a paper page that cannot be found, and takes more electricity. Usability comes from indexing: deciding what metadata each record carries, how records relate to each other, and what vocabulary describes them.
Those decisions cannot be outsourced. They encode how the institution thinks about its own work, and an external team guessing at them will produce a structure nobody uses. Our role is to run the process, propose a scheme, test it against real retrieval tasks, and build what the institution settles on.
Retention before conversion
Not everything should be kept forever, and the law usually has a view. Agreeing retention schedules before conversion avoids digitising material that should have been disposed of, and establishes who may delete what.
Chain of custody
For legal records, how a file moved matters as much as where it ended. Every batch tracked, every handover signed, every image checked for completeness against the file it came from. It slows the work and it is the difference between an archive and a pile of images.
Thirty years out
The format you scan to today will be legacy within fifteen years. Fixity checking, documented migration paths and open formats are not an optional extra. They are the reason the archive still opens when the people who commissioned it have retired.
