As long as the electronic reproduction exactly duplicates the book’s orthography, it is most decidedly a book. A book is no more than its words. There are those who must have the physical features of a book, its binding, the covers, the paper. This is all well and good, but a reader of a Kindle edition of “Finnegan’s Wake” does not lose an iota of Joyce’s intention, as long as it is a faithful reproduction of the text.
