This library was set up as the Central Library for 24 hospitals which are under the direct management of Japan’s Federation of National Public Service Personnel Mutual Aid Associations (of which Toranomon Hospital is a member), as well as 11 hospitals formerly managed by the Association, or a total of 35 hospitals. The Central Library was renovated in 2013 and now has an area of 290 m2, including a reading room and book room. With approximately 5300 separate volumes, 3500 bound journals, and 9000 online journals and book titles, the Central Library provides immediate access to important reading material. It is also a member of the Japan Medical Library Association, which allows the use of many domestic and overseas medical journals while also distributing copies of articles to hospitals. An online and CD-ROM literature search service of the Japan Science and Technology Agency (JST) is also available.
