Recently I was wandering if there is someone or some group preserving , collecting , organizing and publishing all the knowledge of mankind ever created throughout its existence so that if ever mankind faces the 6th mass extinction we don’t have to reinvent the wheel and can have a kick start to our new post apocalyptic civilization .
IIRC the LOC has a copy of every book published in the US… I need to re-verify that, but I believe that was one of the info bits I gathered from my last visit. I don’t retain knowledge very well when I glean it whilst gaping at architecture.
