This topic interests me greatly, as we are part way through barcoding all
maps so they can be lent on the online circulation system.  One of my
hopes is to generate use statistics.  I would love more information on
your activities.  Please send to me if you think the List is not an
appropriate place to enlarge on this topic (though I would expect others
to be as interested as we are)
