On-shelf ranks above loans, ranks above holds
When all items are loaned, the item due soonest is selected
When all items have holds, the item with the least number of holds is selected
When all item resolution determinants are equal (e.g. all items on-shelf) and geographic proximity is enabled and preferred suppliers are not enabled, use geographic proximity to determine the item for resolution
When preferred suppliers are also enabled, use a preferred supplier from the same group.
If more than one supplier in the same group, use geographic proximity OR load balancing to make the selection
Other rules:
Automated load balancing is optional on a per-library basis. (more details to flesh out here)
Preferred groups is optional on a per-library basis.
A library can only belong to a single preferred group.
