Both the Modern Library and Penguin translations provide a detailed plot synopsis at the end of each volume. The last volume of the Modern Library edition, "Time Regained", also includes Kilmartin's "A Guide to Proust," an index of the novel's characters, persons, places, and themes. The Modern Library volumes include a handful of endnotes, and alternative versions of some of the novel's famous episodes. The Penguin volumes each provide an extensive set of brief, non-scholarly endnotes that help identify cultural references perhaps unfamiliar to contemporary English readers. Reviews which discuss the merits of both translations can be found online at the "Observer", the "Telegraph", "The New York Review of Books", "The New York Times", "TempsPerdu.com", and Reading Proust.
