[Machine Translation] After 100 years of work, the "Dictionary of Medieval Latin in the British Archives" was completed in England. It was the result of the combined efforts of volunteer "wordhunters," or language collectors, and the British Academy. Why did the participants push forward with a project that was unprofitable and would not be completed in their lifetimes? The author, a correspondent journalist, visits the people involved, and even expands his interviews to the compilers of Japanese dictionaries. This nonfiction book explores the significance of "language and culture" in today's world that prioritizes efficiency, and also questions the way Japanese people work.
