there are many social subsets, each with its own laws and customs." Scott's process of composition can be traced through the manuscripts (mostly preserved), the more fragmentary sets of proofs, his correspondence, and publisher's records. He did not create detailed plans for his stories, and the remarks by the figure of "the Author" in the Introductory Epistle to The Fortunes of Nigel probably reflect his own experience: "I think there is a dæmon who seats himself on the feather of my pen when I begin to write, and leads it astray from the purpose. Characters expand under my hand; incidents are multiplied; the story lingers, while the materials increase – my regular mansion turns out a Gothic anomaly, and the work is complete long before I have attained the point I proposed." Yet the manuscripts rarely show major deletions or changes of direction, and Scott could clearly keep control of his narrative. That was important, for as soon as he had made fair progress with a novel he would start sending batches of manuscript to be copied (to preserve his anonymity), and the copies were sent to be set up in type. (As usual at the time, the compositors would supply the punctuation.) He received proofs, also in batches, and made many changes at that stage, but these were almost always local corrections and enhancements. As the number of novels grew, they were republished in small collections: Novels and Tales (1819: Waverley to A Tale of Montrose); Historical Romances (1822: Ivanhoe to Kenilworth); Novels and Romances (1824 [1823]: The Pirate to Quentin Durward); and two series of Tales and Romances (1827: St Ronan's Well to Woodstock; 1833: Chronicles of the Canongate to Castle Dangerous). In his last years Scott marked up interleaved copies of these collected editions to produce a final version of what were now officially the Waverley Novels, often called his 'Magnum Opus' or 'Magnum Edition'. Scott provided each novel with an introduction and notes and made mostly piecemeal adjustments to the text. Issued in 48 smart monthly volumes between June 1829 and May 1833 at a modest price of five shillings (25p) these were an innovative and profitable venture aimed at a wide readership: the print run was an astonishing 30,000. In a "General Preface" to the "Magnum Edition", Scott wrote that one factor prompting him to resume work on the Waverley manuscript in 1813 had been
