Hi Byron,

I'm interested to know more about the systems librarian list too. Thank you.

Hi Byron,
I saw your response on he Innovative  Listserve and was curious about the
Systems Librarian Listserve you mentioned.  Could you forward to me
registration information?  The discussions sound interesting and quite
relevant to my day to day activities.  Thanks for your help.
