The circulation rules dictate which patron categories can borrow which material and the limit on each combination. The Default checkout, hold policy by patron category configuration allows you to set the "Total current checkouts allowed" per patron category. It would be good if libraries had the ability to override or set the limit on an individual patron account. For example, a child by default may be allowed to borrow 10 items but the library would like to restrict a specific child to only borrow 5 itmes. This can be achieved with a separate patron category of course but the library would prefer to do it on an individual basis when required.
