Each volume in the Cornell Wordsworth is complete in itself, but no volume supplied tools useful to anyone studying two or more volumes. In this supplementary volume the reader will find a unified index to titles and first lines for the entire series, a guide to the hundreds of manuscripts treated in the twenty-one volumes, and a comprehensive list of the contents of Wordsworth's many lifetime editions. The chance to provide such tools in a volume supplementary to the series made it possible as well to include information that had been omitted from previous volumes and a list of errata for several volumes in the series.

In the third volume are the shorter poems composed between 1807 and 1820, including the Waterloo odes, the fourteen-book Prelude, all eight sonnet series and itinerary poems composed between 1820 and 1845, including The River Duddon, Ecclesiastical Sketches and Yarrow Revisited, poems from the Scottish and Italian tours, and Last Poems, the remaining poems composed between 1821 and 1851.
