The catalog of international tale types (ATU) based on the system of Aarne / Thompson constitutes a fundamentally new edition with extensive additions and innovations. The descriptions of the tale types have been completely rewritten and made more precise. The essential research cited for each type includes extensive documentation of its international distribution as well as monographic works or articles on that type. More than two hundred and fifty new types have been added. A detailed subject index includes the most important subjects, actions, and other motifs, including actors and settings.
