As I read the interim policy for Treaties, we are to code both new and existing authority records as AACR2, but may nonetheless use this AACR2 form in RDA bibliographic records. Correct? OK, as a NACO cataloger, what am I to do with the 667 field (THIS 1XX FIELD CANNOT BE USED UNDER RDA UNTIL THIS RECORD HAS BEEN REVIEWED AND/OR UPDATED) in existing authority records? Normally I would convert the record to RDA and remove the 667, but since I'm not converting to RDA, should I leave the 667 for now, even though we can still use the AACR2 form in RDA bibs? Thanks! Want to make sure I have this right before I address the treaties staring at me from my back-burner. --Lynne _____________________________ --------------------------------------------------- Lynne Griffin, Cataloger LLMC-Digital & LC/JAG Military Legal Resources Saint Louis University Law Library 100 N.
