Hi, I work as a volunteer in a non-profit association that runs the library for culture and religion at the Theological Centre in Meylan near Grenoble in France. My main task is cataloguing. We receive many books through book donations and bequests with the result that we have a large number of duplicates (circa 2500 books out of some 40000). We are setting up a framework to sell the duplicates for a token amount. To this end we have added a item.notforloan value "For Sale" which we use to generate a report of books for sale from which we create a virtual shelf that can be consulted by the patrons. I am trying to figure out how to add a "Price" column with items.price to the Holdings tab of the opac details page for folks viewing the "For Sale" virtual shelf in the "Normal View". The price is shown in the "Marc view". Any advice is gratefully accepted. Thanks, -David Penkler
