Book excerpt: Since its original publication in 1970, Ulysses: the Mechanics of Meaning has become one of the most talked about, cited, and respected of commentaries on Joyce's classic work. Its compact format and its crisp, lucid style make David Hayman's book an essential one for all new readers of Ulysses. For this new edition Hayman has added a convenient chapter-by-chapter account of the action and a substantial afterword extending and amplifying ideas presented in the original edition and briefly summarizing the current critical scene. This makes the book of additional value both to sudents and to the many Joyce scholars who have long depended on the Prentice-Hall edition, now out of print.
