Who wrote the well-known Outline of Chapter Contents in the Penguin edition of Finnegans Wake?
Wikipedia describes the structure of Finnegans Wake as follows.
Finnegans Wake comprises seventeen chapters, divided into four Parts or Books. Part I contains eight chapters, Parts II and III each contain four, and Part IV consists of only one short chapter. The chapters appear without titles, and while Joyce never provided possible chapter titles as he had done for Ulysses, he did title various sections published separately (see Publication history below). The standard critical practice is to indicate part number in Roman numerals, and chapter title in Arabic, so that III.2, for example, indicates the second chapter of the third part.
The Penguin edition of Finnegans Wake includes an Outline of Chapter Contents, which is reproduced at finnegansweb. It begins
