Hi everyone, 
  
There have been two topics discussed on the list recently for which I would like to try to provide some guidance and additional comment: 
  
1) Recording a former AACR2 heading as a variant access point at the time of re-coding to RDA: 
  
·          Make a see reference for the old valid form of heading, with $w nnea, unless the reference itself is a valid RDA variant access point, in which case use $w nne.  In case of doubt, use $w nnea. 
  
Please see the Personal Name NARs FAQ #13 on the PCC web site for examples. The FAQ was also updated recently to cover other RDA guidelines. 
  
Please also remember that the NACO principle of not changing a 1XX unless it has a factual error (as opposed to an error in judgment) remains in place. Closing open birth dates has been an exception to this principle, and now with RDA re-coding, other 1XX’s may be candidates for change. But, for example, if an AACR2 1XX is qualified with a subfield $q, or does not include dates in subfield $d, the 1XX does not need to change at the time of re-coding to RDA, unless another required change is being made to the 1XX such as adding Jr., or deleting a "b." or "d." etc.      
  
2) Order of subfields in 37X authority records in RDA 
  
I was the person who recommended to colleagues at Columbia University: 
  
Subfield $2, if coded, should precede subfield $v or a combination of subfield $v + $u  ...  Aside from that, there is no guidance on placement.  I always put the subfield $2 after the last element to which it applies, and before any subfield $s or $t: 
  
   372 $a Biotechnology $a Genetic engineering $2 lcsh $s 2008 
    not: 
   372 $a Biotechnology $a Genetic engineering $s 2008 $2 lcsh 
  
This can be considered a PCC NACO best practice, but as Richard Moore mentioned, the order does not make any difference to a machine parsing the field, and there is no prescribed order given in the MARC 21 Authority Format. 
  
Thanks everyone, Happy Thanksgiving!
