1xx Introduction

Use fields 100–130 for names or uniform title headings used as a main entry.

If you are inputting current cataloging, construct entries according to Anglo-American Cataloguing Rules, second edition and Library of Congress (LC) practice. Search the OCLC Authority File to verify forms of entry.

Use current LC-AACR2 or AACR2-compatible forms of names and uniform titles. If the current LC-AACR2 or AACR2-compatible form is unknown, construct the heading according to AACR2 and the Library of Congress Rule Interpretations (LCRIs).

If you are inputting retrospective cataloging, search the OCLC Authority File to verify forms of entry.

Use current LC-AACR2 or AACR2-compatible forms of names and uniform titles. If the current LC-AACR2 or AACR2-compatible form is unknown, you may enter the pre-AACR2 form, but you are encouraged to construct the heading according to AACR2 and the LCRIs.

See section 2.2, " Transcribing Pre-AACR2 Copy," for more information.

The Library of Congress has established guidelines for tagging certain corporate bodies and uniform titles. LC's Cataloging Policy and Support Office periodically updates these guidelines and lists of problematic headings. These are available at < http://lcweb.loc.gov/catdir/cpso/ >. Consult these guidelines when constructing problem headings.
