There was entire writeup about this (I think it was posted to HN) that I can no longer find and would be grateful if someone could point me at (my Google-Fu is failing me on this one) that of all the data storage mechanisms we have, paper is the one that we best know how to maintain and preserve. It's nowhere near as "bulky" as people make it out to be, and when done right and taken care of properly, can last centuries.
Here's a link that touches on the topic of preserving info for future generations, a great read: http://www2.library.ucla.edu/about/2483.cfm (What do you preserve? How do you do it? Why? For whom?)
The other article I was referring to earlier pointed out the pitfalls with all the modern "wonders" of storage and how woefully inadequate they would be for attempting to preserve knowledge/data in the big picture. Namely interfaces, specs, requirements, readers, electricity, and all the other goodies that silently play their role in powering your USB stick or bluray disc.
