Greg had argued that the actor may also have played another small role, that of Voltemar, but Duthie disagreed with this view. The publication of the so-called "good quarto" (Q2) of "Hamlet" so soon after Q1 has been explained as the result of the fact that Q1 was so corrupt. Possibly Shakespeare or his company thought it necessary to publish the true text to preserve the author's reputation. The title page states that it is "Newly imprinted and enlarged to almost as much againe as it was, according to the true and perfect coppie". Jonathan Bate states that Q2 is "apparently the one closest to Shakespere's original manuscript, but it may represent a 'reading' text as opposed to a 'performance' one"  The situation is complicated by the fact that the original 1602 entry in The Stationers' Register was made by James Roberts, the printer of Q2, not Valentine Simmes, the printer of Q1. Pollard argued that Roberts was acting on behalf of Shakespeare's company, and that the entry was intended, albeit unsuccessfully, to block the publication of the play by another publisher. Gerald D. Johnson suggests, in contrast, that Roberts made a deal with the bookseller Nicholas Ling, allowing Ling to use another printer to publish Q1 first, but giving Roberts the right to print the much more substantial "good" version later, from which both would profit, with Ling getting to sell the same play twice. While the "bad quarto" theory is still widely accepted, some later scholars have taken a very different view, arguing that the text may be an accurate version of an alternative form of the play. Albert B. Weiner argued in 1962 that Q1 represented a "tourbook" copy, derived originally from a text similar to Q2 or F, which had been trimmed and simplified for performance by a small number of actors on tour in the provinces. But Hardin Craig disagreed in his introduction to Weiner's edition, arguing that Q1 is descended from an earlier draft of the play and that "the second quarto is Shakespeare's revision and amplification of that earlier play." Craig's argument was based on his observation of significant "structural difference" between Q1 and the other texts, that "the first quarto follows the order of events [in the plot] as they appear in Saxo and Belleforest" but that the second quarto, while doubtless a better play, "does not", and in fact interjects "more than 800 lines of other dramatic matter" between the decision of the King and Polonius to spy on Hamlet and the "get thee to a nunnery" scene in which the spying actually transpires.
