Which field feature is characterized by a delimiter and code to separate data pieces within the field?

• A. Two-character indicators
• B. Subfields (Marc)
• C. Field Length
• D. Leader

Answer: (B)

Subfields organize data in MARC fields by using a delimiter symbol to introduce each data element, followed by a code that identifies what that element represents. This setup lets a single field carry multiple pieces of information in a clear, structured way—for example, a title field may include a main title and a statement of responsibility, each in its own subfield like $a and $c. The delimiter marks the start of a subfield, and the code tells you what kind of data follows. The other features don’t perform this internal separation: indicators after the tag modify how the field is interpreted, but they don’t separate data pieces within the field; the Leader is a header for the entire record, and Field Length just describes how long a field is. So the feature described is subfields.
