Sources and Notes

General Reference Works
Works addressing the authorship question as a whole, not tied to a specific candidate or methodology.
IV: Disputed Claims
Where the evidence is actively contested in the scholarly literature, both sides are noted. A site that acknowledges disputes is more defensible than one that pretends they do not exist.
Oxfordian response: Oxfordians typically argue that the name debut is not specifically tied to 1593, or advance a “relay hypothesis” involving a front man or broker. Neither response is supported by primary source documentation. The line is scored on the evidence, not the hypothesis.
Why ~: The securely dated instances (e.g. The Tempest, c. 1610) postdate de Vere’s 1604 death, and the published book was available to any later writer. There is no basis for a distinct score on this line for de Vere.
Why Florio scores ◑ (not ✓): Florio is the translator whose specific phrasing appears in the plays, the closest source proximity of any candidate. But proximity to the source text is not documentation of authorship, so the line yields ◑, not ✓.
The Marlovian argument: That the inquest records a staged death or misidentification, given the intelligence connections of those present (Poley, Skeres, Frizer). This is not impossible but requires primary source evidence to establish.
Downie (2007): Argues the Baines Note and Kyd letters were compiled after Marlowe’s death, changing the picture of May 1593. If correct, the intelligence context of the Deptford meeting looks different. Downie’s argument has not been definitively refuted.
