Hi Maggie,
We run a report annually, and any items that have circulated 3 or more times in the past year get returned, since it costs more to retrieve an item from storage than open shelving. We create a spreadsheet of all items that fall into that category and send it to the unit heads of the different departmental libraries. If anyone would like an item in their collection, they can request it. If not, all items are processed for our main bookstacks. There are some exceptions, such as we wouldn't send a special collections item to the main stacks, or send back one serial volume when the set was in storage, for example. We have not run this report since the pandemic, but we plan to after the new year. If my memory serves me, we typically saw 50-100 items a year returned. I hope that is helpful!
Warm wishes,
Jenny
