Dear all, my name is Paolo and I work as enterprise architect for the Autonomous Province of Bozen-Bolzano (South Tyrol, Italy). We plan to dismiss the old client-server system in use in 200+ German and Ladin school libraries. There are around 60 high schools, 60 medium-sized middle and ground schools and 80 small-sized middle and ground schools. The total number of physical resources is around 850,000 units. I want to propose the introduction of Koha and I would be grateful if you could provide some experiences of the same or higher order of magnitude to be presented as examples. I would also appreciate some technical hints or examples of minimum requirements in terms of hardware and LAMP stack. I thank you in advance and send you in the meantime my best regards. Paolo.
