Which MARC component consists of two character positions at the beginning of a field that provide processing information?

• A. Indicators (Marc)
• B. Subfields (Marc)
• C. Field Length
• D. Leader

Answer: (A)

Two-character indicators are the processing cues placed right after the field tag in a MARC data field. They provide instructions to the cataloging system about how to handle the field—how to index it, display it, or interpret its content. They aren’t the actual data values themselves; those come from the subfields labeled with $a, $b, and so on. Field Length is only stored in the directory to show how long the field data is, and the Leader is the record-wide header at the very start of the record, not part of an individual field. Because indicators give the field-specific processing information, they’re the element described by the question.
