I don't actually know why, but I can imagine a plausible answer: the MARC record does not distinguish between contributors and creators sufficiently well to separate out the x00 fields between them. Either everyone is a creator, or everyone is a contributor, or the main entry (100) is treated as a creator and everyone else a contributor. Whichever it is, some portion of the mapping will be wrong. What would be interesting would be a study that would show the relative ratios of right to wrong in the three (or more?) scenarios. kc Quoting Luciano Ramalho <[log in to unmask]>: > I am mystified by the discovery that the MARC to DC Crosswalk does not > map *any* MARC tag to the DC Creator element! > > http://www.loc.gov/marc/marc2dc.html > > Does anyone know the reasoning behind this strange decision? > > -- > Luciano Ramalho > programador repentista || stand-up programmer > Twitter: @luciano > -- Karen Coyle [log in to unmask] http://kcoyle.net ph: 1-510-540-7596 m: 1-510-435-8234 skype: kcoylenet
