https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=36111 --- Comment #54 from David Nind <david@davidnind.com> --- Testing notes (using KTD): 1. Edited the Books framework to make 856$h visible in the editor 2. Edited Programming Perl (biblionumber=262) to add two entries: Entry 1: . 856$h = https://example.com . 856$y = Non-functioning URL Entry 2: . 856$u = https://example.com . 856$y = Functioning URL 3. Before the patch, clicking on the non-functional URL link opens a blank page. The staff interface and OPAC search result and detail pages all display: Online resources: Non-functioning URL | Functioning URL 4. After the patch: 4.1 The non-functioning URL is no longer displayed: Online resources: Functioning URL 4.2 If there is only one 856 entry AND it has an $h, then 'Online resources' information is no longer displayed in any of the search result or detail pages. (As expected.) 4.3 If a single entry has both an 856$h and an 856$y, it is not displayed. (As expected.) (My reading of the 856 information indicates you shouldn't do this. That is, every URL (whether $h or $u) should have a separate 856 entry.) 4.4 If there is a $u and no $y subfield, then the text displayed in the search result and detail pages is: Online resources: Click here to access online -- You are receiving this mail because: You are watching all bug changes.
