Linguistic Theories of Humor appeared thirty years ago. It attracted a lot of attention and ended up being one of the most quoted books in the linguistics of humor. Partly due to its broad coverage which includes both theoretical and socio-pragmatic aspects and partly due to the depth of its bibliography it remained an indispensable reference in many areas, despite the growth of the field. The original fully corrected text is supplemented by a long essay, in which the author revisits the topics of the book to discuss how three decades have shifted the perspective of the field.
