Shakespeare Authorship: The Importance of Knowing Who Wrote What

Quite beyond 'The play's the thing!' adherence, knowing who actually wrote what in the Shakespeare canon is important for a number of reasons:

• Proper attribution--the authors deserve proper attribution for their works, especially given the impact they've had on literature and life since, and especially considering that whatever led them to cloak their hand is now long passed by history. How important would it be to their descendants to know of their contribution to literature?
  
• Righting magical conception--properly attributing the works to those who might actually have a chance at creating them, by dint of position/situation and education/life experience, rights the fantastical/magical explanation concocted to explain how one without these attributes could have become the greatest writer in English-language history.
  
• Meaning and purpose--knowing proper authorship helps clarify meaning in the works and helps with understanding what motivated their creation, and what was being promoted by their writing.
  
• Historical context--knowing who wrote what and when helps place the works in their proper historical context, further aiding the above.
  
• Behind the scenes--we might learn (finally) what was behind the scheme to place these works behind a pen-name front.
  

Charlton Ogburn has written extensively on this point of importance of knowing proper authorship. His 900-page tome dedicated quite a bit of space and ink to this question. What other important sources on this might exist merits further research.
