The advanced cataloging editor has a z39.50 search form included on the page, but it's just labeled "Search," so it's not at all clear what it's for.
Created attachment 187890 [details] [review] Bug 41015: Label z39.50 search in advanced cataloging To test: 1 - enable and go to advanced cataloging editor 2 - see that the z39.50 search is just labeled "Search" 3 - apply patch, reload page 4 - see it's now labeled "Z39.50 Search"
