Comment 10 for bug 520839

The src to edit should be the retrieveCopyData service in
Open-ILS/web/js/ui/default/staff/circ/services/item.js

Would write a new function to lookup isbn as barcode, then use that function in the existing conditional for the case that copy promise doesn't resolve.

Researching if src code for staff catalog numeric search by isbn can be applied to item status.
