Classification of the plays
Shakespeare's works include the 36 plays printed in the First Folio of 1623, listed below according to their folio classification as comedies, histories and tragedies.[188] 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 scholars agreed that Shakespeare made a major contribution to their composition.[189] 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, his term is often used.[190] These plays and the associated Two Noble Kinsmen are marked with an asterisk (*) below. 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.[191] "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."[192] The term, much debated and sometimes applied to other plays, remains in use, though Hamlet is definitively classed as a tragedy.[193] The other problem plays are marked below with a double dagger (‡).
Plays thought to be only partly written by Shakespeare are marked with a dagger (†) below. Other works occasionally attributed to him are listed as apocrypha.
