Field definition and scope:

Field 130 contains a uniform title used as a main entry in a bibliographic record.  A main entry under uniform title is used when a work is entered directly under title and the work has appeared under varying titles, necessitating that a particular title be chosen to represent the work.  Cataloging rules also prescribe the use of this field when the work is entered directly under title and additions or deletions to the title proper must be accommodated.  In this latter case, the title may not actually vary from iteration to iteration.  The title that appears on the work being cataloged is contained in field 245.  There will be no 100, 110, or 111 field in records with field 130.

The National level record requirement for this field is Mandatory if applicable.

Field 130 is NOT repeatable.

Guidelines for applying content designators:

The content designators identify the subelements occurring in uniform or conventional title, title page title, or series title headings that are not entered under a name in a name/title heading and that are constructed according to the generally accepted cataloging and thesaurus-building rules [e.g., Anglo-American Cataloguing Rules (AACR 2), Library of Congress Subject Headings (LCSH)].

A uniform title heading is used to bring together bibliographic entries for a work when various issues have appeared under different titles and to provide identification for a work when the title by which it is known differs from the title proper of a particular issue or when different publications have identical titles.

A uniform title entered under a name is contained in field 240 or in subfield $t (Title of a work) in the field appropriate for the author's name (X00 Personal Names, X10 Corporate Names, X11 Meeting Names).

Uniform titles used in phrase subject headings (e.g., Bible in atheism) are contained in field 650 (Subject Added Entry - Topical Term).

Content designator history:

First indicator - Nonfiling characters

Values  # - Undefined  [obsolete, 1979]

# - Nonfiling characters not specified  [obsolete, 1980]

The number of character positions associated with a definite or indefinite article at the beginning of a uniform title field that are disregarded in sorting and filing processes was not specified prior to the definition of the first indicator position in 1979.

The interpretation of a # (blank) to indicate that the number of nonfiling characters is not specified was made obsolete in 1980.  Pre-1979 records may contain a # (blank) meaning undefined in this position.

Second indicator - Main entry/subject relationship  (BK MU SE)  [obsolete]:  The use of the second indicator in field 130 to indicate the main entry/subject relationship was made obsolete in 1990.  The values were:  0 (Main entry/subject relationship irrelevant) and 1 (Main entry is subject).

Subfield $d - Date of treaty signing  [new]:  The date of signing of a treaty was not separately subfield coded prior to the definition of subfield $d in 1980.

Subfield $g - Miscellaneous information  [changed, 2014]:  In 2014, subfield $g was made repeatable.

Subfields  $n - Number of part/section of a work  [new]

$p - Name of part/section of a work  [redefined]

In 1979, subfield $n was defined for numbered parts/sections and subfield $p (Part) was redefined to include only named parts/sections.  Prior to that change, both the number and the name of a part were contained in one $p subfield.

Subfield $0 - Authority record control number  [new, 2007]

Subfield $0 - Authority record control number  [redefined, 2010]

In the serials specifications, only subfield $a was defined for field 130 prior to 1980.  The other subfields were defined in 1980.  Data appropriate for these subfields in records created prior to that time may not be separately subfield coded.
