MARC21 Library Standards

Library of Congress
What is Marc record ? A Marc record is a MAchine-Readable Cataloging record
Machine-readable means that a computer, can read and interpret the data in a record. The following pages will explain why this is important and how it is made possible.
Cataloging records come in two types: 1) Bibliographic records, which contain information about a book, serial, sound recording, videorecording, etc., and 2) Authority records, which contain standardized forms for names, titles, and subjects that are used on bibliographic records and provide cross references in catalogs

Call number: The librarian uses a Dewey Decimal or Library of Congress classification schedule to select the call number for an item. The purpose of the call number is to place items on the same subject together on the same shelf in the library. Most items are sub-arranged alphabetically by author. The second part of the call number usually represents the author's name, facilitating this sub arrangement. In other words, it is a system of numbers Dewey Decimal  used to mark and arrange mostly non-fiction books
