PRELIMINARY REMARKS Page Headings With very few exceptions, each page of Narrative Unbound has its own unique name. These names always refer to the two-page spread of Narrative Unbound standing before the reader at any moment in the reading process. In general, the left-hand heading gives the reader immediate access to the line references that define the local and global boundaries of the Four Zoas text being discussed, while the right-hand heading gives the reader a condensed point of reference for the analysis of the lines specified in the left-hand page heading. Like the marginal glosses, the running heads have acquired a life of their own, and thus a version or aspect of the book can be constructed by simply reading the page headings. They form a kind of supra-text, a skeletal framework for the argument of the book. The Graphics The graphics are visual models that picture the structural movement of the narrative in each Night of The Four Zoas by reference to a simultaneous, synchronous pattern that otherwise could not be directly experienced by the reader. Each graphic display provides the reader with a way of thinking about where s/he is situated linearly in the process of reading. These have proved so useful as teaching devices that it seemed appropriate to incorporate them into Narrative Unbound. Except for Nights I and IX, however, the graphics are not an essential part of the argument of the book but are situated at the close of the analysis of each Night to act as retroactive perspectives on the reader's linear journey. Although the descriptive names given to Nights II-VI in the text of Narrative Unbound are taken from the names of the structural maps for those Nights, David Erdman's suggestion that the charts be published separately indicates the degree to which they are independent of the argument of this book. Endnotes The endnotes primarily serve the function of extended marginal glosses. Where alternative or peripheral perspectives would intrude on the text proper or be too long to be inserted in the margins, they have been relegated to notes. In some cases, endnotes contain more technical discussions of textual differences between the 1970 and 1982 Erdman editions of Blake's poetry. Absence of a Separate Index No index for this book has been deemed feasible, since virtually all nominalizations are present on most pages, and the main text contains almost no reference to extratextual matters. Categories that would make sense for an index to Narrative Unbound-such as "characters absent from event x," or "transformations ofy by z"--would generate an index competitive in length with the book itself, would take a very long time to compile, and, in addition, would probably not be usable. Therefore, the functions normally served by conventional indexes have been subsumed by marginalia, page headings, and endnotes Bibliography The bibliography contains works actually cited in the text of Narrative Unbound, works used for epigraphs, and a small selection of works not actually cited but conceptually and methodolog- ically relevant.
