GUIDELINES FOR APPLYING CONTENT DESIGNATORS

Content designators identify the subelements occurring in a title that identifies an item or a series that is not entered under a name in a name/title heading. The title is constructed according to generally accepted cataloging and thesaurus-building rules (e.g., Anglo-American Cataloguing Rules (AACR 2), Library of Congress Subject Headings (LCSH)). Uniform titles used in phrase subject headings (e.g., Bible and atheism) are contained in the X50 fields. A title entered under a name is contained in subfield $t (Title of a work) in the field appropriate for the author's name (X00, X10, X11).

Only generally-applicable content designators are described in full in this section. A small number of content designators with field-specific instructions are described in the Tracings and References-General Information section (for field 430 and 530) and the 7XX Heading Linking Entries-General Information section (for field 730).

INDICATORS

First Indicator - Undefined

Undefined and contains a blank (#).

Second Indicator - Nonfiling characters   [130/430/530]

In field 130, 430, and 530, the second indicator position contains a value that specifies the number of character positions associated with a definite or indefinite article (e.g., Le, An) at the beginning of a uniform title heading that are disregarded in sorting and filing processes.

0 - No nonfiling characters

No initial article character positions are disregarded. Diacritical marks or special characters at the beginning of a uniform title heading that does not begin with an initial article are not counted as nonfiling characters.

130 #0$a"Hsüan lai hsi kan" hsi lieh
130 #0$aElektroshlakovyi pereplav

Initial definite or indefinite articles may also simply be deleted in the formulation of the uniform title heading. If the initial article is retained but is not to be disregarded in sorting and filing processes, value 0 is used.

130 #0$aBastard
[Full title is Der Bastard.]
1-9 - Number of nonfiling characters

Title begins with a definite or indefinite article that is disregarded in sorting and filing processes. Any diacritical mark, space or mark of punctuation associated with the article and any space or mark of punctuation preceding the first filing character after the article is included in the count of nonfiling characters. Any diacritic, however, associated with the first filing character is not included in the count of nonfiling characters. Because the omission of initial articles to be disregarded in sorting and filing processes is common practice, values 1-9 are unlikely to be used in field 130, 430, and 530.

Second Indicator

In field 730, the second indicator position contains one of the values described in the 7XX Heading Linking Entries-General Information section.

When a phrase such as “pianos (2),” “4 hands,” etc., follows a collective uniform title for a specific medium of performance, it is included in subfield $a.

INPUT CONVENTIONS

Ambiguous Headings - See Appendix D: Ambiguous Headings.

Punctuation - Punctuation of the subelements of a heading is generally dictated by descriptive cataloging or subject heading system/thesaurus rules. These input conventions clarify MARC punctuation practices. An X30 field does not end with a mark of punctuation unless the field ends with an abbreviation, an initialism, or data that ends with a mark of punctuation.

130 #0$aTen commandments
130 #0$aGod save the king;$oarr.
130 #0$aTalmud$vOutlines, syllabi, etc.
130 #0$aPublicación miscelánea (Inter-American Institute for Cooperation on Agriculture)
130 #0$aBible.$pN.T.$lEnglish.$sRevised Standard.$f1961?
430 #0$aPax et bonum, Ed.

A mark of punctuation is placed inside a closing quotation mark.

130 #0$wb$aPublicaciones del Archivo Histórico de la Provincia de Buenos Aires "Ricardo Levene."$nIII,$pDocumentos del archivo

130 #0$aMineral resources series (Morgantown, W. Va.)

Display Constant

- [dash associated with the content of subfield $v, $x, $y, and $z]

Dash (-) that precedes a subject subdivision in an extended subject heading is not carried in the MARC record. It may be system generated as a display constant associated with the content of subfield $v, $x, $y, and $z.

 
Content designated field:
130 #0$aBeowulf$xLanguage$vGlossaries, etc.
Display example:
