Thematic chronological search and thematic place name search was serviced formerly by Hitachi Digital Heibonsha (HDH) and is serviced now by Hitachi Systems & Services, Ltd. The service on the Internet was closed in March 2004, but the service called "Encyclopaedia-on-the-Net for Library" is continued at the end of 2004. The developer of the axis search thanks the people in Hitachi Digital Heibonsha and Hitachi Systems & Services that have continued the service for more than five years after he left this job.
