TEST PLAN

0) Apply patch

1) Create an item with a call number in 952$o (e.g. ABC 123)
2) Using the inventory tool, make sure you "Select items you want to check"
which include that item (e.g. Item callnumber between: A and C)
3) Click "Submit"
4) The call number appears in the column marked "Call number"
instead of appearing as [ABC 123] under the library in the
"Library" column
