Comment 4 for bug 1966995

Looking at the code in misc_util.tt2, it looks like an 856 that contains an $n is purposely loop around because it's an asset.uri. I'm assuming this code was written based on $n old definition that was made obsolete in 2020 ($n - Name of location of host [OBSOLETE, 2020]).

We could remove the code above and create a new variable for subfield $n for display purposes.

It also looks like the code to display $z was commented out in summary.tt2 in the Bootstrap opac. Does anyone know why? The only reason I could think of is that it's a repeated field, that would only display one value. It's not commented out in the TPac.
