my hypothesis on the thinking behind this list is that libraries are organisations which are dynamic self evolving complex systems and so i have applied the simple systems theory template to how to merge two libraries. i think the key thing to remember is that systems cannot change radically or quickly and that they depend on feed-back to adjust their equilibrium. that said it follows that any merger, with its implications of big rapid change, will be difficult for any library system. it will be essential to keep open channels of communication and feed-back both within the immediate environment (the law firms themselves) and the external environment (publishers, service providers, journal subscriptions)
