Table of Contents Display and Indexing

If your site has acquired Table of Contents Display and Indexing, you can include table of contents data for monographs in MARC field 970 of bibliographic records. The table of contents data appears on the record display page of your WebPAC. See Using Tables of Contents in WebPAC.

INN-View Table of Contents Data Loading

With a subscription to Table of Contents data via INN-View services, Innovative delivers TOC data in MARC format each month. The system loads TOC 970 fields as additions to the existing records. It makes changes only to the 970-972 fields when updating records. Innovative designed the TOC loader to use minimal resources so it does not interfere with the daily activities on your system.

For MARC 970 field insertion, the system matches TOC data to your bibliographic records based on:

• ISBN
  The loader compares normalized versions of the ISBN in the MARC 020 field of the incoming record and in the existing record. The system normalizes the fields by ignoring all dashes, spaces, and any characters following the ISBN.
• Title
  For title matching, the loader normalizes the MARC field 245 subfields $a, b, and p of the existing record and compares them to the corresponding normalized fields of the incoming record. If the fields match, the record is overlaid. If a title is not cataloged, the loader does not create a new record to receive the TOC data.
• Presence of CAT DATE
• Revision date in the 971 field (used for ongoing loads)
  The TOC loader creates a 971 field to track the date on which the data was last updated on the INN-View machine. This date enables the software to determine whether to load subsequent versions of the TOC data.

Innovative stores author affiliation information in the 972 field. The system loads this field into the N field group as a NOTE. The field appears automatically in your WebPAC among the other NOTE fields. The 972 field is not indexed.

When the system overlays data, it replaces the existing 970, 971, and 972 fields. The system protects these fields when you catalog from other sources and overlay the bibliographic record.

The loaded 970 fields appear automatically in your WebPAC. For more information, see Using Tables of Contents in the OPAC.

The loader rejects a TOC record if the target title is not cataloged or if the title in the incoming record differs from the one in the existing record.

Table of Contents Encoding

There is a separate MARC 970 field for each TOC title or section. Encoding uses the following indicators and delimiters:

Indicators

The first indicator specifies whether the title is indexable.

First Indicator Value	Usage	Indexable
0	Non-distinctive title, such as "Preface"	Not indexed
1	General chapter title or heading	Indexable
2	Citable title (conference paper, short story)	Indexable

The second indicator specifies the hierarchical level for display formatting, such as indentation. The system inserts a blank line when the second indicator reverts to a higher level.

Second Indicator Value	Usage
1	Flush left
2	Indent once
3	Indent twice
4	Indent three times

The following portion of the 970 field is indexed for all fields where the first indicator is 1 or 2.

Field	Description
t	Title phrase index
f	Author phrase index
t,f,d	Keyword index

Delimiters

Delimiter	Usage
l	Section/chapter label
t	Section/chapter title
c	Personal name author in displayed form, such as first_name last_name
f	Indexable personal name or editor in inverted order, such as last_name, first_name
d	Non-personal name author
e	Editor name
p	Page number

The system inserts a forward slash (/) between titles and a comma (,) between authors. Dot leaders precede page numbers, which appear flush right.
