RDA 5.2: Date Abbreviations

Date abbreviations

There are many different abbreviations in $d (i.e., date) of 1XX, 6XX, 7XX, and 8XX fields that can be expanded. The majority of these date changes only take place within X00 fields. NAF Conversion documentation X00 $d (pdf). The main exception is expanding month names in X10, X11, and X30 fields. RDA App. B (html)

Birth date

RDA rules say that there are two possibilities for when the abbreviation b. has been used in a date. The first option is to remove b. and add a hyphen after the birth date. The other option is that b. can change to born. Current LC policy is to add the hyphen after the birth date:

 
 original field:
   100 1  $a Mort, Paul R., $d b. 1894.
  
 updated field:
   100 1  $a Mort, Paul R., $d 1894-               LC policy
       OR
   100 1  $a Mort, Paul R., $d born 1894.
 

Death date

As with the birth date, there are also two options for expanding the abbreviation for a death date. When a d. is encountered, a hyphen can be added before the death date with the d. being removed or else d. can be changed to died. Current LC policy is to add the hyphen before the date:

 
 original field:
   100 1  $a Lewis, Georgina King, $d d. 1924.
  
 updated field:
   100 1  $a Lewis, Georgina King, $d -1924.       LC policy
       OR
   100 1  $a Lewis, Georgina King, $d died 1924.
 

Flourished > active

There are two different ways that fl. or flourished can be changed using RDA guidelines. The first way is to change these to active in the same position of the $d (typically right before the date). The other way to handle this is to expand fl. to flourished. Current LC policy is to change these to active:

 
 original field:
   100 1  $a Brown, John, $d fl. 1854.
  
 updated field:
   100 1  $a Brown, John, $d active 1854.          LC policy
       OR
   100 1  $a Brown, John, $d flourished 1854.
 

Month names

In AACR2, month names were generally abbreviated. In RDA, month names should be expanded. The following table shows the changes that will be made with month names.

   100 1  $a Einhorn, Richard, $d 1952 Aug. 2-
