During an inventory at a place where I used to work we created two computer lists of objects. One list contained all the accession numbers found on the accession cards. The other list contained all the accession numbers found on the objects, providing as Squigle did, arbitrary numbers for objects without accession numbers. By subtracting the list of found objects from the list of cards we could develop a list of missing objects -- cards with no objects. These could be compared to the list of objects with no identification. By subtracting the list of cards from the list of objects we could produce a list of objects that had no accession cards -- an equally valuable bit of information. -- Robert A.
