| The MARC Tags displayprovides
the fullest possible tagged display for a single record from
the Library of Congress Online Catalog.
MARC Tags Display
The MARC Tags display includes the full bibliographic information,
including the "fixed field" or fixed-length data elements and locally
defined fields, with the field tags and content designation specified
by the MARC 21 format,
a communication standard that enables exchange of bibliographic,
holdings, and other data among electronic systems. The leader is
displayed; the directory is not displayed.
All record displays include the call number by which materials
must be requested. Some information displays as a hypertext link
(in blue and underlined). Selecting a link launches a search for
related records. Consult the Full Record
display for the most complete labeled display of bibliographic information.
To focus on subject headings, and any information summarizing and/or
classifying the content of the work, consult the Subjects/Content
display. View the Brief Record
display for the most basic information about the work.
