----------------------------Original message---------------------------- 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) Margaret Eva Geology Library University of Queensland Australia 4072
