Keep write protected master copies, and diskcopy them on to a
"lending" disk whenever anyone wants one.  It takes a little time, but
that's what it takes.  This will protect them from the public.  If you
don't trust the staff (or can't really keep them secure from the
public), then you should do periodic CRC checks which will add more
time to the maintenence.  All this means the library has to have an 
amiga too.
