GUIDELINES FOR APPLYING CONTENT DESIGNATORS
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 245 or in
subfield $t (Title of a work) in the field appropriate for the author's name
(X00, X10, X11). Uniform titles used in phrase subject headings (e.g., Bible in atheism)
are contained in field 650 (Subject Added Entry-Topical Term).
Guidelines for applying all content designators except the second indicator position are
given in this section. A field-specific list of content designators and guidelines for
applying the second indicator position are provided under the description for each
specific X30 field.
■ INDICATORS

(e.g., Le, An) at the beginning of a publication title that are disregarded in

Diacritical marks or special characters at the beginning of a publication title
field that does not begin with an initial article are not counted as nonfiling

formulation of the publication title field.If the initial article is retained but is not to be disregarded in sorting and
filing processes, value 0 is used.
