Dear Eric,
This is the link to pdf: https://xp.fisip-unmul.ac.id/cgi-bin/koha/opac-retrieve-file.pl?id=4ff69d8b703b134d83e7f065f2a34f45

You can search in the title with keyword: military. (result no 1)

For Andy,
Thanks for mentioning another option. I have to learn about Shibboleth first :-} but I will try.

Best regards,
Ketut

It might be possible to hide the link by using CSS. It may depend on the 
method your patrons use to authenticate. We use Shibboleth. When a 
patron is not logged in, the CSS class for <BODY> is "branch-default". 
When the patron is logged in, the class is "branch-LUP". We only have 
one branch, but presumably that would change depending on the branch the 
patron is logged in to.

You could probably use some CSS like

.branch-default .online_resources {
  display: none;
}

This might depend upon which XSLT you're using for the display.
