UNESCO has funding available to use on heritage projects, which could support the existing archive efforts.
The IA is closing in on 30 years, has UNESCO done anything to help the IA during that time?
Have they ever applied?
I don't know, but shouldn't UNESCO when marking something of significance do this kind of research, and reaching out to organizations that are trying (and have been trying) to do essentially what they want to protect?
It is a great way of spreading the word ... many small organizations don't have the man power to do "other things" (like looking up how to apply for strange grants, let alone maybe know about them).
the IA is great for hosting demos too, including running in in-browser emulation. For example see: https://archive.org/details/@deater78
