Off world would help, no atmosphere on the moon for instance makes for less deterioration, and a cave system would shield it from radiation.

On earth clay tablets have done a great job : we have tablets 6000 years old, so we know that works. That’s 60% of 10k already. Titanium seems expensive and might be melted down in time of need, like bronze has been often in the past. Clay tablets survived partly because it’s a ‘worthless’ material.

You need to bury it on the moon. There is a reason the moon is full of holes.

The ones that survived

[prox]

Yeah, but they didn’t even try preserving it! Lots were found in average storerooms and so on.

When there's a lot of things to start with, there's bound to be a lot of things to survive by chance even without preserving. A lot of the stuff that survived was accidentally preserved by nature.

You could say that, but I would point out to its resilience and suitability as a medium for long term information containment. Literally thousands upon thousands have been found. Imagine if one were to try make it last longer :)

[dredmorbius]

With some irony, tablets subjected to the usual destroyer of documents, fire, survive even better as they're vitrified.

It is 60% of 10k, and 0.0006% of a billion years.

But can you engrave them with the precision required for miniaturization?
