The final report summarizing the work of a joint MLA/OLAC task group which worked to address issues connected to 23 additions to the Genre/Form Code and Term Source Codes list (https://tinyurl.com/y7tzhr32), which are utilized in the 33X and 34X fields, was issued in late 2017. The group was charged with examining three issues: inconsistent treatment of RDA and non-RDA terms in MARC 344 and 347, consideration of consistent treatment of MARC 344 and 347 across formats, and implementation of the new $2 source codes.
A question regarding the use of the new $2 source codes was recently raised. Just to be clear, the intent of the recommendation for issue 3 was that whenever separate MARC 34X fields would be required due to multiple applicable $2 source codes, to use separate MARC 34X fields – with the implication that the new source code would also be applied. The latter should have been more explicitly stated. After consultation with Bruce Evans, OLAC CAPC chair at the time and member of the task group, the recommendation for issue 3 has been amended to add the sentence:“Recommend use of new $2 source codes for MARC 34X fields.”
We hope this amendment makes the intent of the group more clear, and clears up confusion over use of the $2 source codes. Catalogers should apply these recommendations, effective immediately. These recommendations will be incorporated into each group’s RDA best practices documents as future revisions are made.
