Hi all, There are often references to MARC on this list but the real influence on the BF vocabulary has been RDA, which we are not in a position to ignore in the bibliographic environment. With RDA you record the attributes of an entity and then an institution can make the Work title or label for that entity as long or short as is needed for the situation. But we are not yet in that environment so we must carry our strings in addition to the pieces. The pieces look a lot like MARC because the pieces called out by RDA look that way, but not entirely: RDA has more, and there is a tendency to want each element in RDA separately identified for manipulation purposes. As RDA matures, BF will follow the progress and adapt as appropriate. Sally *********************************** Sally H.
