CIC maintains a large library gathered expressly for the convenience of Japanese-to-English translators. It includes standard reference works needed for research in the fields of the social science and humanities for which the company has worked since 1990 and a large collection of works about Japanese culture, arts, architecture, and society, and some specialized dictionaries and glossaries available only in print. The list below includes some of the works that translators may find useful when online sources are exhausted or inaccessible.
