Scholars conclude ‘beyond doubt’ that Shakespeare was main author of Edward III

Exclusive: Play anonymously published in 1596 was collaboration between Shakespeare and Christopher Marlowe, according to computer analysis

Dramatic new evidence concludes that the play Edward III should be added to William Shakespeare's canon, and also that it was a major collaboration with his contemporary rival Christopher Marlowe.

The history was published anonymously in 1596, and it has long been thought that Shakespeare wrote at least a few scenes. However, Dr Rory Loughnane, a leading scholar and co-author of the research, told the Guardian that computerised textual analysis pushed the case beyond any reasonable doubt" that the Stratford-born playwright was the principal writer.
