Field 046 is used to record the date elements incumbent with authority data in RDA. This is distinct from the practice of including date(s) in the heading/controlled access point as a means of differentiating instances of identical names. These functions, recording data and constructing access points, are separate and independent. Field 046 does not replace 100 $d. In this case, the heading did not have any dates associated with it except in the equally inscrutable 670 fields. The duplication in the 046 will allow a variety of machine functionality – potential automated matching, potential “on the fly” display of the dates with the heading, or potential automated incorporation of the dates into the heading – should circumstances and system functionality warrant and allow.

Hi all, I would like to know why now with RDA is used now Tag 046 instead of $d in Tag 100?
With this practice, such information is accessible only to librarians that review the authorities being that that 046 is not recovered in OPACs
