To Liz and Jonathan: What you two said is similar: http://wiki.koha-community.org/wiki/Support_for_multiple_PAC_interfaces_by_U... I'm not sure about what you are talking is about independent branches or separated instances. Now we can create a lot of instances with only one Koha installation, each instance has its own database, URL (opac and intranet), and of course they have their own CSS, HTML templates. But it's not what i mean. Branches use only 1 shared database, and all user only need to access to only one URL, and only when they login, they will see different interfaces, based on branch library they registered. If we have only 1 databases for 100 branches, it's easy for us to maintenance, manage, control system preferences. It goes with SYS.Pref Independent branches turn to ON. Sorry for any miss-understanding. Best regards!
