Accessing Japanese language resources using interlibrary loan (ILL) and document delivery (DD) services can be very challenging. This page will give you helpful tips to ensure your ILL requests at your own library are set for a successful transaction. Providing a verifiable source of reference is extremely important because most ILL staff members are not fluent in Japanese and unfamiliar with Japanese publications. They rely on unique record identifiers to locate the items that you request.
If you are affiliated with a North American institution, search first in OCLC WorldCat to find North American libraries that own a copy of the item you are looking for. Find the permalink (unique identifier) for the item and quote the link / identifier on the ILL request form. Note OCLC permalinks can be used for ILL requests for items housed in the National Diet Library (NDL) as WorldCat contains NDL records.
If the item you are seeking is only available in Japan, search in CiNii Books and find the permalink there for the item to be cited on the ILL request form.
See below for more detailed instructions.
1. Go to WorldCat (https://www.worldcat.org)
2. Search for the item you need
3. Open the record and copy the URL in the browser address bar and paste it on your ILL request form. This will enable ILL staff members to locate the correct record of the item you are requesting. The URL can also be copied by clicking on the link icon. Alternatively, the unique identifier ("OCLC number") can be copied from the bibliographic record itself.
