What are good quartos?

Good quartos refer to high-quality editions of literary works, particularly plays and poems, published in the quarto format, which is a book size resulting from folding a large sheet of paper into four leaves. In the context of Shakespeare, good quartos are those that are considered authoritative or reliable, often based on the original manuscripts or closely related to the playwright's intentions. These editions are valued for their accuracy and fidelity to the text, making them essential for scholars and readers alike. Examples include the "First Folio" of Shakespeare's works, which collected many of his plays for the first time.
