Your library should already have a Location Delivery Address entry when you go to . You should be able to edit the address directly from this screen and to save the changes.
When you select from the Location screen, the New Address screen is displayed. The only address types used in LA DOC DEL is Delivery and only one entry for each address type is permitted. Therefore if you have an existing delivery address entry and create a new delivery address entry, this will overwrite the existing delivery address.
!!!Don't forget to update your library's entry in the ILRS Directory !!!
