I just hope there are good archival structures in place in society nowadays, because there are a lot of theaters worldwide performing plays known and unknown every day, but AFAIK only the best known ones get statues made and I don't believe they contain a list of their works (for example).

I mean that would make sense; make sturdy statues of authors / playwrights / etc, and embed copies of their work in a compartiment inside of them or in the material itself. Lose a few in interesting looking hills.
