The plays printed originally in quarto format were branded fraudulent by the editors of the First Folio, Heminge and Condell, who wrote in the Preface to their collection that fans of Shakespeare's works had been cheated by "diverse stolen and surreptitious copies, maimed and deformed by the frauds of injurious imposters that expos'd them." They believed that most of the quartos in circulation had been either stolen outright by unscrupulous printers who plagiarized the official prompt-books belonging to Shakespeare and his company or they had been horribly reconstructed from the memory of people who had seen the plays performed. Heminge and Condell were right to be concerned about the integrity of Shakespeare's great works. The flaws in some of the quartos are wretched.
