Photos of books Yoon Dongju bought and collected mostly during his time in Yonhui College. As the poet was leaving the country to study in Japan, he left these books to Kang Cheojung (1917–?), and the books were later handed over to and preserved by the bereaved family until they were donated to Yonsei University. The poet’s collection includes books from various fields, including English and French literature, German philosophy, aesthetics, etc.
