ABSTRACT
On the Machine readable cataloging (MARC) format, the bibliographic information of each record is separated into different parts, such as author, title, publisher and extra. A one-digit numeric code that follows the tag and precedes the field. For some fields, two numbers are used, one giving instruction to the computer for processing information, and the other providing information about the content of the field. MARC consists of a system of inputting the cataloging information on the computer following a standard devised by the Library of Congress. This standardized format allows other libraries to share the data, the computer to interpret the data, and users to retrieve the data. As a library technician whose job involves cataloging, chances are that library technicians will be working at a computer terminal. As in the card environment, where pieces of information are arranged on the card, in the computer environment, the necessary information requires its proper place.
