i would agree with you and even go a little further - i could see zng
replacing the current generation z39.50 in traditional library
applications at some point - it depends on how widely it gets adopted and
the types of information it enables those applicatiosn to get to - if oclc
ues it and it also allows an ils to get other non traditional information
sources - a case can be made for it - at some point everyone is going to
need to decide how long they want to keep the old systems around - even
though we already have it deployed we do update our systems and eventually
it may become baggage we dont want to (or cant afford to ) maintain and
keep updated
