When searching the catalog, each item in a record is listed with a number in parenthesis in the location column. Usually this number is (1). When I inspect the code, it is surrounded by a span with a class of "item_count". It appears that it is a count of items with the same location and call number. I would propose that it is pointless to show the count if it is 1. Most items are going to be a single copy. The count is only useful if it is higher than one. I would suggest not showing this number unless it is higher than 1.
