[Allegro] Contents notes in MARC: jetzt auch Inhaltsverzeichnisse

[B.Eversberg]

Etwas Neues zum Thema Anreicherung von Katalogen.

Das MARC-Feld 505 "Contents note", oft benutzt zur AUflistung der 
Bandtitel bei mehrteiligen werken, wird jetzt von der LC zusätzlich auch 
für die Angabe von Inhaltsverzeichnissen verwendet.
Nachfolgend die Original-Mitteilungen aus der "LC Cataloging newsline" 
Nr. 13/6
US-OPACs indexieren in Ermangelung sonstiger Felder oder Sätze für die 
Titel von Bänden meistens die 505 im allgemeinen Stichwortregister. 
Daher wohl die Entscheidung, die 505 auch für diesen neuen Zweck zu nutzen.

MfG B.E.

                  MACHINE-GENERATED CONTENTS NOTES

      On Feb. 1, 2005, the Library of Congress began enriching
bibliographic records with scanned table of contents data in field
505,  adding information that was previously available only through
856 links.  The 505 data are generated from the table of contents
information and supplied by computer program.    They will be
preceded by the legend: "Machine-generated contents note:"   The
505 indicators for these  machine-generated notes will be set to
"8" (no display constant generated) and blank (Basic; single
occurrence of subfield $a).

      Since the scanned tables of contents come in a wide variety of
formats and structures, some errors are to be expected in the
placement and configuration of the 505 textual strings.  Space,
hyphen, hyphen, space will be inserted after each line break within
the tables of contents. Chapter and page numbers will appear as
captured from the scanned tables-of-contents images.  The 505 data
will not undergo review for punctuation.   Below is a sample 505:

      LC records with existing 856 links to tables of contents texts
will be batch-processed, modified, and redistributed on a daily
basis until all the approximately 60,000 records containing links
from the 856 to LC's web-based DTOC (digital tables of contents)
records are enhanced.   The 856 links to the DTOCs will remain in
the records.

      This effort makes tables of contents information more readily
available within MARC records and increases access to these data.

records may be directed to John Byrum <jbyr at loc.gov>, (202)
