So you're an admirer of James Joyce 's "Ulysses"? Well, thank Trieste for that book. Why? Gordon Bowker's "James Joyce: A New Biography" (Farrar, Straus & Giroux: 608 pp., $35) shows readers how living in that seaport city in northeastern Italy helped rekindle Joyce's enthusiasm after the lackluster reception of "Dubliners" and his uncertainty over what readers would think of "A Portrait of the Artist as a Young Man." The city not only gave him and wife Nora an income, it gave Joyce, as a teacher, an exceptional pupil: the writer Ettore Schmitz, known by the pen name Italo Svevo.
