MARC Elements and Tags Matching

This question asks us to connect different parts of a library catalog record, known as MARC 21 elements, with their specific numeric codes, called tags. This is a fundamental skill in library science for organizing and retrieving information.

MARC Personal Main Entry (A)

The 'Personal Main Entry' is used when the most important person associated with a work (like the author) is listed as the primary heading in the catalog record. In the MARC 21 format, the tag used for this purpose is 100.

Therefore, element A (Personal Main Entry) correctly matches with tag III (100).

MARC Personal Subject Heading (B)

A 'Personal Subject Heading' is assigned when a specific person's name is the main subject of the resource being cataloged. For example, a biography about a historical figure would use this element. The MARC 21 tag for personal name subject headings is 600.

Thus, element B (Personal Subject Heading) matches with tag IV (600).

MARC Personal Added Entry (C)

The 'Personal Added Entry' is used for other individuals who played a significant role in creating the work but are not the main entry. This could include co-authors, editors, or illustrators. The MARC 21 tag designated for these additional personal name entries is 700.

Consequently, element C (Personal Added Entry) pairs with tag I (700).

MARC Bibliographic Title (D)

The 'Bibliographic Title' refers to the main title and subtitle of the work, as found on the item itself. It's essential for identifying the resource. In MARC 21, the comprehensive tag for the title statement is 245.

Therefore, element D (Bibliographic Title) corresponds to tag II (245).

MARC Mappings Summary

To summarize the correct pairings between the MARC 21 elements and their tags:

This detailed mapping confirms the correct combination is A-III, B-IV, C-I, D-II.

MARC Tag Explanations

Understanding the function of each MARC tag helps in creating accurate and searchable library catalog records.

MARC Tag 100: Main Entry - Personal Name

Tag 100 is used for the primary author or creator when their name is the main access point for the item. It's crucial for identifying the work by its creator.

MARC Tag 700: Added Entry - Personal Name

Tag 700 provides alternative access points based on personal names. It's used for co-authors, editors, illustrators, and other contributors whose names are important for locating the resource but are not the main entry.

MARC Tag 600: Subject Added Entry - Personal Name

When a personal name is the subject of the work (e.g., in a biography or critical study), tag 600 is used. This allows users to find resources about specific individuals.

MARC Tag 245: Title Statement

Tag 245 contains the main title of the work, often including subtitles and sometimes preliminary statements of responsibility. This is the primary textual identifier for the resource.
