The First Folio is the first comprehensive collection of Shakespeare’s plays, containing 36 of the 38 plays we now consider to be his. It was published in 1623, seven years after Shakespeare’s death, by some of the actors from his company. It was the first time a number of Shakespeare’s plays, including Macbeth and As You Like It, were published at all. Without the First Folio we might have only about half of the plays that Shakespeare ever wrote.
