Have you heard of Biblio Battle? Biblio Battle is a new style of book review competition that incorporates a game-like element. Each participant has five minutes to give a presentation on a book they would like to recommend, and then together they hold a discussion and choose a "Champion Book." This event is not only for book lovers; it is now spreading to elementary and junior high schools, universities, and training sessions and study groups at companies. How did Biblio Battle come about? What is its appeal? And what are some hints for "winning"? To answer these questions, we spoke to Professor Tadahiro Taniguchi of Ritsumeikan University's College of Information Science and Engineering, the creator of Biblio Battle.
