Ask Slashdot: Permanent Preservation of Human Knowledge?
Wayne2 writes "While there have been many attempts to preserve human knowledge in electronic format, it occurred to me that these attempts all assume that human civilization remains more or less intact. Given humanity's history of growth and collapse with knowledge repeatedly gained then lost, has anyone considered a more permanent solution? I realize that this could be very difficult and/or expensive depending on how long we want to preserve the information and what assumptions we make regarding posterity's ability to access it. Alternatively, are we, as a species, willing to start over if we experience a catastrophe, pandemic, etc. of significant magnitude on a global scale that derails our progress and sends us back to the dark ages or worse?"

Books. It worked before, it should work again.
The electronic preservation angle was my wife's thesis.

Please note that they weren't fired, originally. They didn't have that much fuel in Mesopotamia to fire everything they wanted. Ironically, many of the preserved tablets come from libraries that burned down in random fires. These events stopped being celebrated by archaeologists after Middle Easterners switched to other writing materials around 100 CE.
Ezekiel 23:20
Periodically send up long distance spacecraft loaded with not just data but the means to view it and the means to rebuild from first principles, assuming a child was viewing it - here is how you find iron deposits, mine and refine them, this is how you forge ploughs, these are the basics of algebra. Have them programmed to circle around somewhere just inside Jupiter's orbit, and have multiple stations here on earth sending out a deadman signal - when they stop broadcasting, the vessels begin to return in waves seperated by ten years or so, with the last waves arriving once a century.
When they make it home, have them attempt to locate likely inhabited areas whether by thermal imaging looking for fires at night or just vegetation profiling for fields, then drop down nearby, broadcasting light and sound, even radio, until someone comes to investigate.
It's relatively easy to permanently preserve all of mankind's knowledge, just pack it in a rocket and send it Oort-cloud bound. Well permanently as in astronomical timescales. The trick is to preserve all of humanity's knowledge in a way that's useful to humanity in the future.
While that's true to some extent, it doesn't mean that knowledge shouldn't be preserved in a format that would be accessible by a recovering civilization. Just because they don't have electricity now, doesn't mean they never will, and a handy guidebook telling them how those things work will speed things up later.
It does mean though, that the information should be prioritized - there's a T-shirt/poster floating around the internet full of "things to take credit for discovering if you go back in time". Most of the items it lists are either critical discoveries that led directly to improvements in quality of life, or were the basis for other technologies. Pasteurization, antibiotics, electric generation, radio, flight, and more. (It's here by the way.)
A guide like that is a good start - build things up in stages, add in more (useful) detail, never assuming that the reader will already have a tool unless it has already been explained how to make it. Then if you want to go hog-wild, after you've reached the part explaining how to make a computer and digitize information, put the stuff that would require a heavily industrialized civilization into a digitized code format and explain how it's encoded, so they can read it when they're ready/able to use it.
Random data being used for research though, is likely totally useless. Not only is the DNA/RNA sequence from that rat likely to be useless to a recovering civilization, depending on what sort of cataclysm happened, the DNA/RNA of a rat may not even match what was recorded. Leave stuff like that to DNA/Seed banks, unless it's part of an explanation of "what DNA/RNA is", and even then, the whole set is pointless. (Also probably patented.) A Tokamak reactor may not be useful to a low tech civilization, but with the boost provided by being taught how to make hydro-electric generators, lights, heaters, radios, and internal combustion engines (they can run on cheaply made alcohol, they're just less efficient that way, and wear out faster.), they might be able to make use of that information in only a few generations.
The real problem of course, is format, and ensuring that not only does the information survive, but that these future people are able to understand it when they do see it, rather than thinking "Oh, pretty metal plates with squiggles on them. I bet I could melt those down and make a great set of knives out of them."
Oh sure, that will work for very low densities of information, but what about something the size of the Wikipedia? That article states that the Wikipedia has over 2.4 billion words across over 4 million articles. The article has a nice visual image of what would happen if you took all that information and printed it into 1000 page encyclopedia volumes (each containing 8 million characters). It totals over 1800 print volumes.
Now, where are you going to find that much stone writing surface in one place, and how are you going to economically carve it in a reasonable lifetime, and how are you going to arrange it in a fashion that it's human readable/explorable?
Even reproducing something immensely valuable for a recovering industrial society like Machinery's Handbook in stonework would take an immense amount of space, time, and money to do. Just something as simple as the Georgia Guidestones cost about $225,000 to do.
No, try again when you come up with something practical.
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
I would suggest using material that will not be used for firestarter.
