RDA 4.6: Other Field Additions
046 fields are useful when your dates cannot be correctly coded in X00 $d due to B.C. dates or incorrect dates being used (1). This may be another means to make that date available or understandable:
original: 100 $a Cory, David, $db. 1872 260 $a New York :$b Cupples & Leon Co., $c 1921 [i.e. 1964]. updated: 046 $a x $c 1921 100 $a Cory, David, $db. 1872 260 $a New York :$b Cupples & Leon Co., $c 1921 [i.e. 1964].
In this instance, due to the [i.e. 1964] date, the rule takes the date preceding the i.e. date and places that into the 046 field. The x designates that we are working with an incorrect date and the c subfield lets us know that this date is part of the Common Era. This same rule would apply if the 260/264 $c had a B.C. date.

Special Note for the 38X fields
Currently Backstage only adds the 382, 383, and 384 fields derived from the 240 field.
38X fields can be added to your records to correspond with music headings in a way to help break up the original music heading into a more machine-actionable set of fields (2). In particular, 382 fields (Medium of Performance) chunk the music heading's medium into its own field: RDA 6.15.1 (html)
original field: 100 $a Telemann, Georg Philipp, $d 1681-1767. 240 $a Suites, $m string orchestra, $r D major. added field: 382 $a string orchestra
In this example, the 240 $m is mapped to 382 $a to denote the Medium of Performance.
MARS 2.0 processing will not attempt to add a 382 field if any of the following is present:
- 382 field already exists in record
- 240 field has $k, $o, $p, "brasses", "plucked instrument", or "keyboard instruments"
- 240 $m contains "strings", "woodwinds", "winds" and 240 $t does not contain "trio", "quartet", or "quintet"
original fields: 100 $a Hoffmeister, Franz Anton, $d 1754-1812. $t Quintets, $m violins, violas, cello, $r A major 100 $a Bonazzi, F. $q (Ferdinando), $d 1746-1845. $t Sonatas, $m organs (2), $r C major 100 $a Huybrechts, Albert, $d 1899-1938. $t Suites, $m piano (Sketches) added fields: 382 $a violins, violas, cello 382 $a organs (2) 382 $a piano
original field: 100 $a Callhoff, Herbert, $d 1933- 240 $a Quartets, strings, $n no. 2 added field: 383 $a no. 2
In this example, the 240 $n is mapped to 383 $a to denote the Numeric Designation of Musical Work. NAF Conversion documentation 383 field (pdf)
original field: 100 $a Johann Joseph Ranier Rudolph, $c Erzherzog von Oesterreich. 240 $a Sonatas, clarinet, piano, $n op. 2, $r A major added fields: 384 $a A major
In this example, the 240 $r is mapped to 384 $a to denote the Key.
Parenthetical information is typically discarded when mapping to 384 fields: NAF Conversion documentation for 384 field (pdf)
original fields: 100 $a Dowland, John, $d 1563?-1626. $t Galliards, $m lute, $n P. 31, $r G minor 100 $a Mozart, Wolfgang Amadeus, $d 1756-1791. $t Requiem, $n K. 626, $r D minor (Süssmayr) 100 $a Torelli, Giuseppe, $d 1658-1709. $t Solos, $m violins (2), $r D minor (Ms. British Library. Additional 64965, no. 9(a)) added fields: 384 $a G minor 384 $a D minor 384 $a D minor
