[Web4lib] Restricting OPAC to just catalog and databases?

[Stacey McKim]

(Hi!  I'm sorry if this has already been covered, but I
didn't have any luck searching the archives...)

How do people restrict their OPACs to just their online
catalog and subscription databases?  It's my understanding
that there's software that does this... what do people
recommend?

More information about my situation, in case it matters: 
this fall, we are finally upgrading from  dumb-terminal
OPACs (with no online access).  We'll be installing Unicorn,
with them hosting us remotely.  So, our in-house OPACs will
essentially be free-standing internet stations.

Thank you so much!
