Hi, A preliminary series of patches implementing part of the proposed system group functionality is available for review and comments at http://arwen.metavore.com/~gmc/patches/sysgroups/ The patches include: * adding parent/child relationships between libraries * allowing item types and patron categories to be "owned" by a specific library. * changes to the circ rule editor to show only the item types and categories that apply to the selected branch or are inherited from its ancestor libraries. * an option to restrict the locations a non-superlibrarian can log in for * an option to restrict the branches a staff operator is allowed to set circ rules for If you decide to apply the patches and test, please note that there are a couple schema changes, which for now can be installed by running installer/data/mysqlupdatedb_sysgroups.pl.
