LONDON (AP) — Oxford University Press says its new edition of William Shakespeare's works will co-credit Christopher Marlowe on the three Henry VI plays.

The decision announced Monday for the upcoming edition comes after a team of scholars using modern analytical methods revisited the question of whether Shakespeare collaborated with others. The research suggests that experts underestimated the extent to which Shakespeare collaborated with others.

The publisher says that "identifying Marlowe's hand in the Henry VI plays is just one of the fresh features of this project."

The experts included Gary Taylor of Florida State University and John Jowett at the University of Birmingham.

The authorship of Shakespeare's works has long been disputed, with one theory being that philosopher Sir Francis Bacon is the true author of the works.
