For increased accuracy, each page was keyed by two different typists in order to identify and correct discrepancies

This was a common practice used for systems that took data entry via punch cards as well (during the punch-card era).

Modern practice for things that undergo a D-A-D transition is to include a secondary (often lossy compressed) representation that can be used to validate that the data was correctly replicated.

I love that we can now achieve the same result with a single line of code

    >>> for backword in sorted(line[::-1].strip() for line in file('/usr/share/dict/words')): print backword[::-1]

and I wonder what ideas are tedious now that will be similarly trivial 80 years from now... probably biological ones
