RDA 7.0

STEP 7.0 : AUTHORITY CONTROL

rda authority control

In November 2010, Backstage created several authority control options for processing RDA bibliographic records (040 $e). Since that time we have refined these options with help from our clients. Currently we have 7 separate options to choose from:

• 1.0 - AACR2 & RDA against AACR2 only
• 2.0 - AACR2 against AACR2; ignore RDA
• 3.0 - AACR2 against AACR2; RDA against RDA (1st), AACR2 700-4 (2nd)
  • 3.5 - Same as 3.0 except: unmatched AACR2 against RDA; unmatched RDA against AACR2
• 4.0 - AACR2 & RDA against AACR2 (1st), AACR2 700-4 (2nd)
  • 4.5 - Same as 4.0 except: unmatched AACR2 against RDA
• 5.0 - AACR2 against AACR2 (1st), RDA (2nd), AACR2 700-4 (3rd); RDA against RDA (1st), AACR2 700-4 (2nd), AACR2 (3rd)

Regardless of which authority control option is chosen, there are several of our bibliographic validation rules that are not run on RDA bib records. This includes:

• Subfield Updates and Deletes (namely any rules that remove relator terms)
• Field Conversions and Additions
• GMD Standardization

rda master authority file

In order to facilitate authority matching in RDA bib records, Backstage has created a separate master authority file of RDA authority records. This includes any authority record with 040 $e rda as well as any AACR2 authority record with 7XX x4.
