I have almost 15,000 titles in which there is no narrator listed, as per the narrator headings list. I can't run a query with nothing in the field. How do I pull up these narrator-less books so I can begin to properly categorize them?
You can query for "is blank" as your operator to find these titles.
Also, remember that if you have any BR or LP titles, the narrator should be Blank for those titles! I recommend limiting your query to DB to find titles that may actually need correction.
