I was looking at Mark Anderson's Shakespearebyanothername blog archive today and came across links to his August 2006 essays on Gather.com. The essays are a persuasive intro to the authorship question.
Part I: The enigma and the Shakespeare code
Part II: Gentle Master William
Part III: The 1604 question
Anderson's March 4, 2006 entry in his archive includes an extensive -- and brilliant -- commentary by our chairperson, Tom Hunter.
