STORY: Normalization MARC Authority record

covers normalization rules for removing punctuation in MARC bib records.

And adds rules for parentheses and square brackets.

The purpose of this card is to apply comparable normalization rules to MARC Authority records to ensure consistency / uniformity for transforming MARC data into data graph data.

Punctuation normalization rule - preceding subfield

1. Check the MARC Authority record for the presence of a subfield from the list below.

"XX0$c": [","],

"XX0$d": [" ;", ","],

"XX0$v": [" ;", ","],

"110$b": ["."],

"111$c": [" :"],

"111$d": [","],

"111$q": ["."]

2. When a subfield from the list exists in the MARC Authority record, check for any trailing punctuation in the subfield that precedes the matching subfield.

e.g. 111$d": [","] → If the MARC Authority record includes a 111$d subfield, the rule says to look for a trailing comma in the subfield that immediately precedes the 111$d subfield.

Where there is a match, strip the trailing punctuation from the subfield. Else keep the value intact.

3. Repeat process for each punctuation normalization rule that applies to a particular MARC field

NOTE: Normalization rules involving a period mark (.) need further inspection before stripping a trailing period mark from a subfield. These rules are outside the scope of this card and addressed, separately, in . For the scope of this card, treat trailing periods like any other punctuation per the normalization rules.

Examples:

Naoe, Hiroji

Original MARC Authority record

Check for punctuation normalization rule

From the list, there is a match on the rule for 100 $d

"XX0$d": [" ;", ","],

which instructs to check for the presence of a trailing semicolon (;) or comma (,) in the preceding subfield.

Inspect preceding subfield for trailing punctuation that matches punctuation normalization rule

The preceding subfield (100 $a) does have a trailing comma, which should be stripped to normalize the value.

Rinse and repeat: Check for any other punctuation normalization rules for the record

No other punctuation normalization rules apply

Gautama Buddha

Original MARC Authority record

Check for normalization rules

Matches on 100 $c and 100 $d

“XX0$c": [","]

Inspect preceding subfield for trailing punctuation that matches normalization rule

For 100 $c rule, check for trailing comma in preceding subfield → 100 $b

Rinse and repeat

For 100 $d rule, check for either trailing semicolon or trailing comma in preceding subfield → 100 $c
