Eligible HeadingsAuthority records are permanent records in machine-readable form that include the followingelements: 1) the form of the name chosen for use in headings (1XX); 2) the sources for thisform and variant forms (670); and 3) the cross-references leading to the heading from variantforms or from related headings (4XX and 5XX) if appropriate. Additional information may berecorded in fixed fields (008) and cataloger's notes (667, 663, 664, etc.). Control data andcontent designation are also included for proper identification and manipulation of themachine-readable data. The non-NACO form of name preferred by the appropriate nationalcataloging agency may be recorded in a linking reference (7XX).Generally, a name authority record is made for any title, person, corporate, meeting, orgeographic name heading that may be used as a main or added entry heading (includingsubject added entries) or in certain cross-references. NARs may also be made for headingsused only in certain cross-references and for geographic or corporate names that are used asqualifiers in headings. NARs are not made for personal names when the only clue to theperson's identity is a non-alphabetic or non-numeric device (See DCM Z1, Introduction), norfor entities that may be used only as subject entries, e.g., topical subject headings, fictionalcharacters, animals, or geographic features.NACO participants may contribute name authority records for titles or name/titles (other thanseries, see below) as needed for cataloging. At LC an authority record for a uniform title isrequired only when one or more of the following conditions applies (See DCM Z1,Introduction):a) a reference must be traced on that authority record; or,b) special research done to establish the heading must be recorded; or,c) the heading is needed for a related work added or subject entry, and nobibliographic record for the item exists in the database; or,d) special information needs to be recorded, e.g., citation title for a law.At LC these criteria are applied to each element of the full heading (main title, language, part,etc.) and a separate authority record is made for each element that meets the criteria.Note that this means that authority records are not automatically created for each element ofa uniform title heading.Types of headingsAll name headings are eligible for contribution to NACO, including:personal name headingscorporate body headings13
