We would carve Wikipedia's most important articles in stone.

Wikipedia has a set of 1000 "vital articles" that would be a major asset in rebuilding civilization.[1] Of course, the internal details of the encyclopedia's organization, its Talk pages, esoteric editorial conflicts, Pokemon pages, etc. are irrelevant and would be omitted for a version of the encyclopedia put onto truly durable, readable storage media.

A few years ago, while talking with a Wikipedian about the Long Now Foundation,[2] he said something that has stuck with me:

"Who says it's not in the Wikimedia Foundation's mandate to commission certain articles to be etched in stone?"

I would love to see that goal advertized in one of the WMF's annual fundraising banners. It would be so much more awesome than investing in improved default typography (not that the exquisite new typography [3] isn't nice).

Naturally, there would need to be several language versions and many copies of the stone-etched Wikipedia articles. A more durable storage medium than stone would also be a good idea. And having the articles assumes people in the post-apocalyptic world could read an existing major language to a reasonable degree. Having a gradated table of contents, such that more fundamental and simple concepts came before sophisticated ones (e.g. 'sanitation' before 'vaccine', 'arithmetic' before 'calculus') would also obviously be helpful.

Most of the vital articles that would help in rebuilding civilization [1] are in bad condition. Maybe this discussion will inspire someone to push one of those articles to a better state.

[1] https://en.wikipedia.org/wiki/Wikipedia:Vital_articles. The vital articles are divided into 11 categories. Of these, the following 300 or so articles from 6 of those categories would probably be the most helpful in rebuilding civilization:

- Everyday life: clothing, cooking, job, writing, and various major languages.

- Geography: city, Beijing, Cairo, Delhi, Jakarta, London, Mexico City, Moscow, New York City, Rome, Sao Paulo, Singapore, country, Africa, Antarctica, Asia, Europe, Oceania, North America, South America, Arctic, Middle East, sea, Atlantic Ocean, Indian Ocean, Pacific Ocean, lake, river, land, desert, forest, glacier, mountain, Alps, Andes, Himalayas, Rocky Mountains

- Health and medicine: common cold, influenza, pneumonia, burn, tuberculosis, ageing, antibiotic, vaccine, sanitation
