Automated Authority Control & the Human Component: How We Do What the Computers Can’t. Karla Geerlings Head, Serials & Authorities Unit, MU Libraries. Historically, catalogers were required to verify each and every controlled heading as they cataloged.

Bib record Transaction file
Both new and updated records go through the transaction file and are matched against the local authority file.
Changes to older records WILL NOT be sent for vendor processing.
-Author, LC Subject, MeSH
-Author, LC Subject, MeSH, Title
-Author, LC Subject, MeSH, Title
Bibs with current update dates which contain headings which are were unique within our database when they hit the list.
Heading matches authority 4xx field in local authority file
Generated by cross-checking 001 and 019 of new or changed records
Lists bib records that were not updated by the local auth. control as the heading in the bib record did not exactly match a heading or SEE reference (4XX) in an authority record. Possible causes:
The cluster report (called “rotational” report at UM) contains items with multi-site “owners”:
PLUS AACP-generated categories…
AACP is an automatic process in Millennium which compares new and updated authority records (loaded/ changed locally or through vendor processing) with the local database, making changes when needed.
-Author, MeSH, LC subject, title
-Author, MeSH, LC subject, title
-Author, title, subject
Authority record heading doesn’t match any bibliographic record heading in MERLIN
These are reviewed to deicide:
Actions: leave alone (not blind), code for deletion (blind, unneeded), code as intentionally blind (Conference heading, etc.)
Indicates there are two authority records with the same see reference (4XX) (in the local authority file), and the computer cannot differentiate for “flipping” existing bibs
These are reviewed and corrected, if needed
Lists corrections made by the computer during processing (incoming authorities against existing bibs)
These are reviewed to be sure the change was appropriate
Ex.: IEEE in 4XX in local
(3 in OCLC, 1 in local)
Incoming record: Instituto
Español de Estudios Estratégicos
This happens when someone imports an authority when it already exists in the local authority file
We review to find which has the most up-to-date information
The bib record has no known location code (rarely happens at UM used to occurred w/record loads)
We try to determine who loaded the record and what may have happened
If we cannot locate the owner and no records are attached, we delete
None of these can be resolved satisfactorily by a computer program; the human error must be untangled by a human
Changes are reviewed and searched in the local database to determine if:
Reports LCSH split headings. We have these applied to all bibs. with old heading, but must check for completeness
Old 650 0 $aJewels$vCatalogs.
New 650 0 $aGems$vCatalogs.
New 650 0 $aInsignia$vCatalogs.
New 650 0 $aJewelry$vCatalogs.
New 650 0 $aPrecious stones$vCatalogs.
We review these to determine:
Reports where the ǂa of a Uniform Title, Author or Subject Heading matches an authority record, but the rest does not match an authority. We look for:
This report largely inconsequential
These occur mostly with geographic subjects, names not yet established and name/titles with no matching name/title authority. We look for:
which might match
Happens when a heading matches an authority in another index or is coded for a different use:
100 0 $aM. (matches a series authority)
We can usually straighten these
out, but takes some intuition and
knowledge of local practice,
especially for series titles.
Reports MARC tags flipped during processing; we check for appropriateness.
… context might say Kansas (Musical Group)
Although we are not supposed to receive this report, we do check to be sure something else was not meant.
651 1 $aYukon$vPoetry
These are almost always miscoded in the 2nd indicator, and should be LCSH
Mostly Canadian local headings
(65x _5), which we handle in other ways through LCSH
We also review for miscoding here
Local subjects with no corresponding Local authority record
Again, mostly Canadian (65x _5)
Filing indicators point to an initial article which is not evident to the computer.
740 20 $aWhite dawn is stealing.
What was actually meant:
740 02 $aWhite dawn is stealing.
“Headings in this report matched a heading in the authority file, but the usage codes in the authority record indicate that the heading is not appropriate for the use to which it has been applied in the bibliographic record. An example would be when the authority record indicates that the heading is appropriate for use as a main or added entry, but the heading has been used as a series added entry.”
610 10 $aEngland and Wales.$bSovereign (1625-1649 : Charles I)
Flags words which may be initial articles(language-dependent) but which are not coded as such. Correct as needed.
110 20 $aA & M Telephone Company
246 33 $aA day in the life of Today's Dental
246 3_ $aA la Convention nationale
A, An, Los…
Reports headings in subfield z which are unrecognized because:
We look for:
Metadata located by machine processing, transferred into catalog records by machine processing, checked by machine process follow a scripted formula and usually produces coherent headings, BUT:

100 1 Emblems, Author of The choice.
