One of my favorite books. But, he wasn't using animagraffs, was he? I seem to recall him burying a bunch of books in plastic, possibly in the ground?

There's a pretty well known concept around writing "Restart Civilization" texts (They make an appearance in another niven/pournelle book, The Mote in Gods Eye) - I just think the animagraffs would be a useful addition to the tools in which to do so.
