Query: Should have been an article, not a book

The material here might have been considerably better served had it been edited down to a journal article size. Additionally, there are a number of typographical and spelling errors that distract from or alter the meaning of the text, including one in the table of contents' description of the first chapter! Also, the preface refers several times to Conrad's novelette as "The Heart of Darkness," but further into the book, the authors seem to have learned that there is no "The" in the title. Might seem nit picky to some, but I believe that any teacher of English literature would know this, and so it is difficult to avoid wondering just how much one can trust this text.I do like the idea of the "triangular" seating arrangement.
