We have made available a preliminary draft of a MARC 21 Authority field mapping to MODS elements. We are currently developing a tool to convert MARCXML authority records to MADS and will probably discover the need for some changes when we are finished and are testing it. In the meantime, consider this a preliminary draft for comments. Comments may be sent to this list or directly to me, [log in to unmask] The mapping is at: http://www.loc.gov/standards/mads/mads-mapping.html Rebecca ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^ Rebecca S.
