Originally a Japanese form that flourished in the seventeenth and eighteenth centuries, haiku has seen a tremendous growth in popularity in the English language over the last two decades. It is a type of poetry that celebrates simplicity, emotion, and imagery, one in which only a few words convey worlds of mystery and meaning. This third edition, now completely revised and updated, comprises 850 haiku and senryu (a related genre, usually humorous and concerned with human nature) written in English by 89 poets, including the top haiku writers of the American past and present. A new foreword details developments since the publication of the last edition.
