Thanks, Mike. Your answer, below, sounds like an elegant solution. Since Evergreen is designed for scalability, maybe it could support a national or global consortium, which would be more user-friendly than current Inter-Library Loan (ILL) procedures.

The rules are based on organizational proximity, item age, item type
and locally defined rules that can look at many attributes of the
items, requesting patrons and even staff, if a staff member is placing
a hold for a patron.
In PINES, there are three levels to the hierarchy: Consortium, System
and Branch. And, of course, this hierarchy is installation specific,
so it can be as deep or broad as is needed.
The short version: the system first looks at other organizational
units within the pickup location's parent organization (the System of
a Branch in PINES) and targets items there. The targeting rotates
daily, so if the first item targeted is not captured then it rolls to
another at the same proximity. If there are no available copies in
the pickup location's parent organization then it looks farther up the
hierarchy (the entire Consortium in PINES) and the same daily
targeting rotation occurs on those items. There are also various ways
to affect which copies can and cannot be transited between different
levels of the hierarchy, including optional proximity protection for
newly added items based on their age.
We also plan to add geospacial information and the possibility of
administrator supplied route weighting to the hold targeting system so
that Evergreen can better decided which copies will fulfill the
All of this is integrated directly into the cataloging and circulation
workflow, so that it's just a matter of setting attributes on copies.
The one exception is scripted rules which are supplied using simple
:) ), though this is mainly used for very specific (and rare)
overrides of the general targeting rule system.
