I figured since HN was mainly "hackers" (builders, tinkerers, doers) that this would be a good forum for this type of open ended question.
I was primarily interested in if the answers would be centered around self-preservation, rebuilding of society, rebuilding of technology, or preservation of the arts and philosophy.
Second, I was interested in real, pragmatic solutions that people were implementing.
For example, since the paper book is becoming less and less important in our daily transfer of information, then less and less is being written on paper about knowledge in building, agriculture, and technology. If "google it" becomes impossible for the common citizen, what would they do for information?
I know in my own personal life, I am reasonably accomplished in the academic area, and working professionally as a software engineer. However, I have not bothered to commit to memory the breadth of information required to sustain myself and my family if we were suddenly thrown into a "dark ages" situation.
