I understand why it is not a good idea to digitize, as tampering might be easier to do without any traces, but why do they store wills for 150 years? One would think that by then they are outdated and no longer needed.
Edit: looks like the concern is about historical artifacts. Feels even more ridiculous than I thought. What's next, taking pictures of historical paintings and destroying originals? Why not digitize and still keep the originals?
