The 'Related databases' function automatically displays databases related to the search keyword at the top of the search results list screen.
For example, if you enter the keyword 'Yomiuri', the YOMIDASU REKISHIKAN will appear at the top of the search results.
This is convenient as it allows you to quickly access databases related to the keyword.
Note that this function cannot be used with the library's OPAC (PCs installed for searching in the library).
