Shakespeare's Tragedy of Romeo and Juliet

The earliest edition of Romeo and Juliet, so far as we know, was a quarto printed in 1597, the title-page of which asserts that "it hath been often (with great applause) plaid publiquely." A second quarto appeared in 1599, declared to be "newly corrected, augmented, and amended."

Two other quartos appeared before the folio of 1623, one in 1609 and the other undated; and it is doubtful which was the earlier. The undated quarto is the first that bears the name of the author ("Written by W. Shake-speare"), but this does not occur in some copies of the edition. A fifth quarto was published in 1637.

The first quarto is much shorter than the second, the former having only 2232 lines, including the prologue, while the latter has 3007 lines (Daniel). Some editors believe that the first quarto gives the author's first draft of the play, and the second the form it took after he had revised and enlarged it; but the majority of the best critics agree substantially in the opinion that the first quarto was a pirated edition, and represents in an abbreviated and imperfect form the play subsequently printed in full in the second. The former was "made up partly from copies of portions of the original play, partly from recollection and from notes taken during the performance;" the latter was from an authentic copy, and a careful comparison of the text with the earlier one shows that in the meantime the play "underwent revision, received some slight augmentation, and in some few places must have been entirely rewritten."
