Excerpt from The Complete Works of William Shakespeare
Our best authority for the text of Othello is the folio of 1623; but a quarto derived from an independent manuscript had appeared in the preceding year, and had been entered in the Stationers' Register in October 1621. The occurrence of many oaths and expletives in the quarto which do not appear in the folio suggests the idea that the manuscript from which the former text was produced may have been a transcript ppeceding in date the enactment against swearing passed early in the reign of James I. A few lines absent from the folio are found in the quarto but a far larger number of lines about l6o wanting in the quarto are found in the folio. Some of these differences apparently arose from.care1essness in printing the quarto; some omissions were probably made to shorten the perform ance of the play a few lines may be additions of the author, found in the manuscript used for the folio. The subsequent quartos of 1630 and 1655 are of com paratively slight importance in ascertaining the text.
