Hi, filter are very useful function if holdings view. If librarian manage hold request on periodical item (issue) isn't easy to find specific item from many. Filters allow sort items or find specific item very easy and quick. For newspapers or magazines we shoudl use Serial enumeration / chronology.

Adding filters to hold request page would definitely help placing an hold on a specific volume of a serial.
There is a filter now on top of the item table on the 'place hold' page in the staff interface.
