===1.0 - AACR2 & RDA against AACR2 only===
+
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).
−
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).
+
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.
  
−
This option does not match 700 x4 in AACR2 authority. It also does not match against the RDA authority file at all:

AACR2 bibs are treated the same as in option 1 above (AACR2 1xx/4xx only). However, RDA bibs are separated and effectively ignored during processing. These ignored RDA bibs can then be searched at a later date by the library or delivered separately/combined as desired.

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:

Matched headings (either AACR2 or RDA, respectively) are updated to the 1xx version within the authority file. If no match is found for RDA bibs against the RDA authorities, then this option searches the AACR2 700-4. If it matches at this point, the RDA bib heading is updated to reflect the version within the AACR2 700-4 heading.

AACR2 bibs continue to start their initial searching similar to the previous options listed above (1st = AACR2 1xx/4xx). However, if there is no match against the AACR2 1xx/4xx, then the system proceeds to check the RDA authority file. A match at this point changes the AACR2 bib heading to the RDA 1xx version (returning the RDA authority as a matching record).

===option 2 - separate out rda bibs===

RDA bibs are treated the same as in the first couple steps of option 3 above (1st = RDA; 2nd = AACR2 700-4). Where it diverges is when there is no match against the AACR2 700-4 heading. In these cases, option 3.5 further attempts to find a match against the AACR2 1xx/4xx. A match at this point yields the 1xx version of the AACR2 authority.

RDA OPTION 1.0

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 2.0

Rda.2.0.gif

AACR2 bibs are treated the same as in option 1 above (AACR2 1xx/4xx only). However, RDA bibs are separated and effectively ignored during processing. These ignored RDA bibs can then be searched at a later date by the library or delivered separately/combined as desired.

AACR2 bib search order:

  1. AACR2 1xx/4xx

RDA bib search order:

  1. no search



RDA OPTION 3.0

Rda.3.0.gif

Once again, AACR2 bibs are treated the same as options 1 & 2 above in this option (AACR2 1xx/4xx only). However, RDA bibs are now searched against the RDA authority file initially. Matched headings (either AACR2 or RDA, respectively) are updated to the 1xx version within the authority file. If no match is found for RDA bibs against the RDA authorities, then this option searches the AACR2 700-4. If it matches at this point, the RDA bib heading is updated to reflect the version within the AACR2 700-4 heading.

AACR2 bib search order:

  1. AACR2 1xx/4xx

RDA bib search order:

  1. RDA 1xx/4xx
  2. AACR2 700-4



RDA OPTION 3.5

Rda.3.5.gif

AACR2 bibs continue to start their initial searching similar to the previous options listed above (1st = AACR2 1xx/4xx). However, if there is no match against the AACR2 1xx/4xx, then the system proceeds to check the RDA authority file. A match at this point changes the AACR2 bib heading to the RDA 1xx version (returning the RDA authority as a matching record).

RDA bibs are treated the same as in the first couple steps of option 3 above (1st = RDA; 2nd = AACR2 700-4). Where it diverges is when there is no match against the AACR2 700-4 heading. In these cases, option 3.5 further attempts to find a match against the AACR2 1xx/4xx. A match at this point yields the 1xx version of the AACR2 authority.

AACR2 bib search order:

  1. AACR2 1xx/4xx
  2. RDA 1xx/4xx

RDA bib search order:

  1. RDA 1xx/4xx
  2. AACR2 700-4
  3. AACR2 1xx/4xx



RDA OPTION 4.0

Rda.4.0.gif

AACR2 bibs continue to start their initial searching similar to the previous options listed above (1st = AACR2 1xx/4xx). However, if there is no match against the AACR2 1xx/4xx, then the system proceeds to check the AACR2 700-4 heading. A match at this point changes the AACR2 bib heading to the AACR2 1xx version.

RDA bibs are treated similar to option 1 above (1st = AACR2 1xx/4xx). If no match is found, then the RDA bib heading is searched against the AACR2 700-4 heading. In both cases, the AACR2 1xx version is the preferred change to the original RDA bib heading.

AACR2 bib search order:

  1. AACR2 1xx/4xx
  2. AACR2 700-4

RDA bib search order:

  1. AACR2 1xx/4xx
  2. AACR2 700-4



RDA OPTION 4.5

Rda.4.5.gif

AACR2 bibs continue to start their initial searching similar to the previous options listed above (1st = AACR2 1xx/4xx; 2nd = AACR2 700-4). However, if there is no match by this point, an attempt is made against the RDA authority file. A match yields the 1xx version of the RDA authority in place of the AACR2 bib heading.

RDA bibs are treated exactly the same as in option 4 (1st = AACR2 1xx/4xx; 2nd = AACR2 700-4).

AACR2 bib search order:

  1. AACR2 1xx/4xx
  2. AACR2 700-4
  3. RDA 1xx/4xx

RDA bib search order:

  1. AACR2 1xx/4xx
  2. AACR2 700-4



RDA OPTION 5.0

Rda.5.0.gif

If there was one other potential default for a library to choose for their RDA authority control processing, this option might be a good fit. This option searches logically based on initial record type (AACR2 or RDA), but only changing to the authorized 1xx version of the respective authority file.

AACR2 bib search order:

  1. AACR2 1xx/4xx
  2. RDA 1xx/4xx
  3. AACR2 700-4

RDA bib search order:

  1. RDA 1xx/4xx
  2. AACR2 700-4
