Personally I used the paper version whenever I wanted to check things 
out. That probably wasn't as often as I use the internet to check stuff 
because I didn't have that much need then. I still use the CD version of 
Britannica if I want to be reasonably sure of some idea before 
researching it further.

There is little value to the economy from being able to settle a pub 
bet. Or to furnish an argument on USENET or facebook.

One would, I think need to establish that the work was being used for 
educational purposes that 'matter' educationally, and those that had 
read the material were better as a result.

Unfortunately the coverage of history, philosophy, geography, and arts 
subjects are unreadable and almost worthless.

EXAMPLE:

      Charles IV died in 1328, leaving only a daughter,
      and an unborn infant who would prove to be a girl.

no modern writer writes like that.

EXAMPLE:

     The senior line of the Capetian dynasty thus ended,
     creating a crisis over the French succession.

There was no crises in France about it. Philip VI took over in the same 
way that Charles IV had succeeded. Both examples come from two 
successive sentences in the 100 years war article. The rest of the 
article is riddled with such stupidities.

To Government that would be a net loss as they would otherwise be able 
to collect taxes on profits.
