There are many other aids for a thorough study ofThe Prelude and its background. A chronological table enables the reader to contextualize the biographical and historical allusions in the texts and footnotes. "References toThe Prelude in Process" presents the relevant allusions to the poem, by Wordsworth and by members of his circle, from 1799 to 1850. Another section, "Early Reception," reprints significant comments on the published version of 1850 by readers and reviewers. Finally, there are seven critical essays by Jonathan Wordsworth, M. H. Abrams, Geoffrey H. Hartman, Richard J. Onorato, William Empson, Herbert Lindenberger, and W. B. Gallie.
