1XX's Main Entries

    100    Main entry—personal name

    110    Main entry—corporate name

    111    Main entry—conference name

The 1XX fields are for the various types of main entry. The AACR2 rules allow for main entry under personal names, corporate names, and conference names. All of these are assigned different tags in this section. A tag is also available for uniform titles, which are used for works such as the Bible, for anonymous works, or for works that may be known by several variations of the title, but need to be filed under one chosen version for ease of searching (i.e. fairy tales, classic literature, etc.) The indicators and subfields for these fields help to indicate details of these names, such as a more complete name for an author using initials.

In this example from the sample record, the main entry is a 100 tag, indicating that it is a personal name. The use of a ‘1’ in the first indicator field shows that the name has a single surname and a forename. There is only one subfield, which has the code ‘a’, indicating the personal name.
