It would be nice if Koha tracked that an item was on reserve at some point and when it was on reserve it checked out X times. Versus the data of all of it's checkouts.
Theoretically (I haven't tried) you should be able to possibly get this data out of old_reserves with a report?
Rereading this I think Nicole was referring to course reserves - not holds. Changing the title.
Yes it was in regards to course reserves
