  Shakespeare's works include the 36 plays printed in the First Folio of 1623, listed according to their folio classification as comedies, histories, and tragedies. Two plays not included in the First Folio, The Two Noble Kinsmen and Pericles, Prince of Tyre, are now accepted as part of the canon, with today's scholars agreeing that Shakespeare made major contributions to the writing of both. No Shakespearean poems were included in the First Folio.
  
  In the late 19th century, Edward Dowden classified four of the late comedies as romances, and though many scholars prefer to call them tragicomedies, Dowden's term is often used. In 1896, Frederick S. Boas coined the term " problem plays " to describe four plays: All's Well That Ends Well, Measure for Measure, Troilus and Cressida, and Hamlet. "Dramas as singular in theme and temper cannot be strictly called comedies or tragedies", he wrote. "We may, therefore, borrow a convenient phrase from the theatre of today and class them together as Shakespeare's problem plays." The term, much debated and sometimes applied to other plays, remains in use, though Hamlet is definitively classed as a tragedy.
