Running Tips/Guidelines: This report is designed to show those titles with patron requests against them greater than a specific number. Libraries can use this report to determine whether or not they should purchase another copy of the title(s) in question. The number of requests is based on individual library and not across the entire library system.

The report here is shown with number of requests greater than 5. You can change the 5 to whatever value you desired - HAVING count(all_holds.bib_id) > 5
