Given our recent issues with large publishers blocking us from scraping them directly, it would be very useful to fallback to getting our metadata from archive.org. In the process we could fetch the archive URL and data and feed that into the template (similar to T115224).
Original description:
This is a total wishlist, but it would be nice if (when given a URL that 404s) citoid attempted to pull something from archive.org instead of saying (more or less) "you can construct this manually".
