 Jones' investigation was first published as "" (in "The American Journal of Psychology", January 1910); it was later expanded in a 1923 publication; before finally appearing as a book-length study ("Hamlet and Oedipus") in 1949.Freud had originally linked the writing of "Hamlet" (with its oedipal subtext) to the death of Shakespeare's father in 1601, but had to abandon this view when he gave his support to the Oxfordian theory of Shakespeare authorship – something Jones always rejected in his study.In 1986, the historian Peter Gay described "Hamlet and Oedipus" as "still controversial", noting that the work has been criticized as "literal-minded and unliterary".
