LCSH to FAST Conversion
MARS 2.0 now has the capability of converting Library of Congress 6XX fields to FAST, where an equivalent occurs. Original LC 6XX fields will be retained and the new FAST 6XX fields will contain the proper $w source as well as the $0 URI.
FAST Authority Records will be available for export should you need them.
