Information:
The Subject Added Entry - Uniform Title (630 tag)
of the MARC 21 bibliographic record contains a
uniform title for a work used as a subject heading.
The 630 tag contains the title for an anonymous
work or a work for which many people share
responsibility. This allows library users to find
items about the Bible, the Arabian Nights, the Dead
Sea Scrolls, the Koran, individual motion pictures,
and other such works. Titles of work with
individual authors are entered in the 600 tag
subfield t.
Chapter 25 of AACR2, "Uniform Titles", contains
rules for constructing uniform titles for use as
headings. This chapter contains sections on
headings for laws, treaties, sacred scriptures,
liturgical works, and musical works.
RDA 6.2 provides guidelines on recording titles
of works.
Uniform titles used as subject headings may be
modified by the use of subdivisions. The use and
application of these subdivisions are determined by
the controlled vocabulary list the library uses. In
the United States the most popular subject heading
lists are the Library of Congress Subject
Headings and the Sears List of Subject
Headings. Consult the subject heading list of
your choice for the use and application rules and
guidelines.
Subfield a of the 630 tag usually contains the
established form of the uniform title. Subfield f
includes the date of a work to distinguish it from
editions published at a different date. Subfield k
contains a form heading, usually Selections.
Subfield l tells the language of a translation.
Subfield n contains the number of a part of the
work in subfield a, and subfield p contains the
name of a part. Use subfield x for general
subdivisions. Use subfield z for a geographic
subdivision. Use subfield v for a form subdivision.

Library of Congress Subject Headings (LCSH)
and LC's Names Authority List are designed for LC's
own collection and are used by many large public
libraries, college and university libraries, and
special libraries. LC's lists are comprehensive,
and have a number of free-floating subdivisions
that can be added to uniform titles.
630 00 _aBeowulf
_vJuvenile sound recordings.
630 00 _aQur'an
_vPrayers.
630 00 _aBible
_xCriticism, interpretation, etc.
630 00 _aBible
_vExaminations, questions, etc.
630 00 _aAve Maria.
The Library of Congress Subject Headings for
Children's Literature or Annotated Card (AC)
generally use the LCSH version of uniform titles.
Use of Hail Mary for Ave Maria is an exception.
630 01 _aHail Mary.
Sears List of Subject Headings is designed
to meet the needs of small and medium-sized
libraries. In Alliance Plus we use the Library of
Congress Name Authority List for uniform titles in
Sears headings. Sears provides a smaller list of
subdivisions than LCSH. The example shows a case
where Sears uses a different subdivision from the
Library of Congress.
