Question

Control Information, Number and Codes have the following : (A) Field Number (B) ISBN (C) ISSN (D) DDC Choose the correct answer from the options given below:

• A. (A), (B) and (D) only
• B. (A), (C) and (D) only
• C. (A), (B), (C) and (D)
• D. (B), (C) and (D) only

Hint:

Think of "Control Information" in a catalog record as the data that computers use for sorting, linking, and identifying, rather than the data humans read for description. ISBN, ISSN, and DDC numbers all fit this role.

Answer 1

The Correct Option is C

Step 1: Analyze the category "Control Information, Number and Codes". This category in bibliographic formats like MARC refers to data fields that contain unique identifiers, classification numbers, and other coded information used for processing and managing records. These are distinct from descriptive fields like title or author.

Step 2: Evaluate each option against this definition. \[\begin{array}{rl} \bullet & \text{(A) Field Number: This is a fundamental part of the control information, as it identifies the specific data field (e.g., 001 for Control Number, 020 for ISBN).} \\ \bullet & \text{(B) ISBN (International Standard Book Number): A unique numeric identifier for books. This is a classic example of a control number.} \\ \bullet & \text{(C) ISSN (International Standard Serial Number): A unique identifier for serial publications. This is also a standard control number.} \\ \bullet & \text{(D) DDC (Dewey Decimal Classification) number: A classification code used to organize library materials by subject. It is a form of coded information.} \\ \end{array}\]

Step 3: Conclude. All four items—Field Number, ISBN, ISSN, and DDC—are types of control information, numbers, or codes used in bibliographic records. Therefore, all are correct.
