==STEP 7.1 : RDA AUTHORITY CONTROL OPTIONS==

==RDA OPTION 1==
 +
[[Image:rda.1.0.gif]]<br><br>
 +
Inasmuch as there can be a default for authorizing your headings when it concerns RDA, this option may be a good starting point. This is useful for libraries that are not yet ready to embrace RDA (or never plan to do so).
  
===option 1 - aacr2 & rda -> aacr2===
+
AACR2 and RDA bibs are processed in the same manner for this option. Both are treated as if they were AACR2. Matching is made solely from the 1XX/4XX headings within the AACR2 authority. Matching headings are then updated with the 1XX version of the AACR2 authority.
This is the MARS 2.0 default processing option for your RDA bibs.  
+
  
When an AACR2 authority already exists, current LC policy inserts an RDA authority heading into the AACR2 authority master as a 700 field with 2nd indicator 4. If an AACR2 authority does not exist, then a new RDA authority is generated (040 $e rda).
+
Unmatched headings are added to a report and retained as-is within the respective AACR2 or RDA bib.
 +
<br><br>

AACR2 bib search order:

#AACR2 1XX/4XX
  
This option does not match 700 x4 in AACR2 authority. It also does not match against the RDA authority file at all:

#AACR2 1XX/4XX
 +
<br>
 +
==RDA OPTION 2==
 +
[[Image:rda.2.0.gif]]<br><br>
 +
AACR2 bibs are matched to 1XX and 4XX fields in AACR2 authority records. Matched headings are updated to the 1XX form. RDA bibs are not processed in this option.  They are separated and effectively ignored during processing. These ignored RDA bibs can be delivered separately or combined as desired. They can then be searched at a later date by the library.

MARS 2.0 copies all AACR2 authorities with 700 x4 into our RDA master. In this scenario, the old 700 x4 (RDA) becomes the new 100 field in the RDA master, with the previous 100 field (AACR2) becoming a new 400 field:

RDA bib headings are also matched against the 1XX and 4XX fields in AACR2 authorities. Matched headings are updated to the 1XX form. Unmatched headings are then matched against 1XX and 4XX fields in RDA authorities. Matched headings are updated to the 1XX form.
RDA bibs are separated out to not process at all, and instead saved or discarded as desired by your library:

+
If an AACR2 heading does not find a match against the modified AACR2 master (which includes the 700 x4 for this option), then the unmatched heading is
+
checked against the RDA master.
+
 
+
At this point in the process, the RDA master will consist of new RDA authorities only, with no equivalent in the AACR2 master (i.e., no AACR2 with 700 x4 has been converted to an RDA authority to match against).

RDA OPTION 1

Rda.1.0.gif

Inasmuch as there can be a default for authorizing your headings when it concerns RDA, this option may be a good starting point. This is useful for libraries that are not yet ready to embrace RDA (or never plan to do so).

AACR2 and RDA bibs are processed in the same manner for this option. Both are treated as if they were AACR2. Matching is made solely from the 1XX/4XX headings within the AACR2 authority. Matching headings are then updated with the 1XX version of the AACR2 authority.

Unmatched headings are added to a report and retained as-is within the respective AACR2 or RDA bib.

AACR2 bib search order:

  1. AACR2 1XX/4XX

RDA bib search order:

  1. AACR2 1XX/4XX


RDA OPTION 2

Rda.2.0.gif

AACR2 bibs are matched to 1XX and 4XX fields in AACR2 authority records. Matched headings are updated to the 1XX form. RDA bibs are not processed in this option. They are separated and effectively ignored during processing. These ignored RDA bibs can be delivered separately or combined as desired. They can then be searched at a later date by the library.

RDA bib search order:

RDA OPTION 3

AACR2 bibs are matched against 1XX and 4XX fields in AACR2 authorities. Matched headings are updated to the 1XX version.

RDA bibs are matched against 1XX and 4XX fields in RDA authorities. Matched headings are updated to the 1XX version.

Unmatched headings in AACR2 and RDA bibs are left unchanged and added to a report.

RDA bib search order:

  1. RDA 1XX/4XX


RDA OPTION 4

AACR2 bib headings are first matched against 1XX and 4XX fields in AACR2 authorities. Matched headings are updated to the 1XX form. Unmatched headings are then matched against 1XX and 4XX fields in RDA authorities. Matched headings are updated to the 1XX form.

RDA bib headings are also matched against the 1XX and 4XX fields in AACR2 authorities. Matched headings are updated to the 1XX form. Unmatched headings are then matched against 1XX and 4XX fields in RDA authorities. Matched headings are updated to the 1XX form.

Any AACR2 or RDA headings that are still unmatched are left unchanged and added to a report.

AACR2 bib search order:

  1. AACR2 1XX/4XX
  2. RDA 1XX/4XX

RDA bib search order:

  2. RDA 1XX/4XX


RDA OPTION 5

This option follows the PCC/LC standards.

AACR2 bib headings are first searched against the 1XX and 4XX fields in AACR2 authorities. Matched headings are updated to the 1XX form. Unmatched headings are then matched against the 1XX and 4XX headings in RDA authorities. Matched headings will be updated to the RDA 1XX form in the RDA record. Any headings that are still unmatched are left unchanged and added to a report.

RDA bib headings are first searched against 1XX and 4XX fields in RDA authorities. Matched headings are updated to the 1XX form. Unmatched headings are then matched against the 1XX and 4XX fields in AACR2 authorities and matched headings are updated to the AACR2 1XX form.

Any headings that are still unmatched are left unchanged and added to a report.

AACR2 bib search order:

  1. AACR2 1XX/4XX
