 note = {application/pdf, This study aims to clarify the availability of the textbooks in the syllabus of 1,243 courses offered by the Faculty of Letters, Chuo University, in the academic year 2020. Three ways to obtain the textbooks were assumed: 1） borrowing them from the university library, 2） purchasing them from online bookstores, and 3） borrowing them from e-book services for libraries. As a result, about 90% of the textbooks were held by the library. About 80% of the Japanese books were available for purchase at online bookstores. On the other hand, only 20% were available as e-books. Even in the e-book services for libraries, less than 15% of the textbooks were provided as e-books. As online education becomes more and more popular, it is necessary to develop e-book services, whereas the conditions for expanding them are still insufficient. Libraries need to be prepared to provide both printed books and e-books in an  appropriate manner.},
