When you have XSLT on in the opac the results are showing the locations followed by the call number with no spaced - so: Library[123.21] This is a trivial thing, but there should be a space in there for easier reading.
I fixed that one a long time ago, I thought. One of my XSLT patches -- am trying to locate which one.
Looks like I didn't send a patch for it -- maybe I'm remembering a local customization. I can fix it when I get a chance, unless someone else wants to do it before I get to it.
