Hello, We are trying to develop a system of clearly identifying duplicate object numbers in TMS. Previously many of the curatorial departments maintained their own numbering lists for study collection works, since they were not full collection works. We are now entering these into TMS and discovering duplicate numbers. Most of these duplicates share a "root" number, but due to an addition of parts or components in the number, TMS does not recognize them as duplicates: SC194.2002, SC194.2002.1-3. During our conversion, Gallery gave duplicate numbers a "Dupl" suffix to distinguish them, but we are looking for another way to denote these records in our system. If you have any suggestions or examples of how you've resolved this problem in your own collection, I would greatly appreciate it! Many thanks, Eliza Sparacino Manager, Collection and Exhibition Technologies (212) 708.9599 [log in to unmask] MoMAQNS The Museum of Modern Art, Queens http://www.moma.org
