Oxfordian theory and writings
Waugh is an advocate of the Oxfordian theory, the belief that Edward de Vere, 17th Earl of Oxford wrote the works of William Shakespeare. He claims to have found surreptitious allusions embedded in 16th- and 17th-century works revealing that the name "William Shakespeare" was a pseudonym used by Oxford to write the Shakespeare oeuvre. He is a life member of the De Vere Society,  and serves as the Honorary President of the Shakespeare Authorship Coalition.
