How Disciplines Work in Summon 2.0
Discipline Mapping in CDI
Subject Terms
Disciplines mapped via Subject Terms are mapped in two ways:
-
HILCC (Hierarchical Interface to Library of Congress Classification) subject terms associated with authority titles in 360 KB and Ulrich's
-
Subject Terms in an item-level Summon record that have an exact match
Examples:
-
Journal of Ecology's authority title in 360 KB is associated with HILCC subject terms "Biology - General," "Botany - General," and "Ecology"; therefore, the Biology, Botany, and Ecology Disciplines are mapped.
-
A dissertation about the rise of African rice farming has a subject term Botany; therefore, the Botany Discipline is mapped.
-
An article from the Journal of Environmental Management has a subject term Forestry, and the journal's authority title in 360 KB is associated with HILCC subject terms "Economic History" and "Environmental Sciences"; therefore, Economics, Environmental Sciences, and Forestry Disciplines are mapped. The discipline "Economics" is applied, rather than the narrower term "Economic History", based on the level of disciplines mapped in CDI.
Call Numbers
We map Disciplines via the Library of Congress Call Number, Dewey Number, or National Library of Medicine (NLM Classification).
Examples:
-
LCCallNum value is within the range of BJ1801 to BJ2195; therefore, the Anthropology Discipline is mapped.
-
DEWEY value starts with the number 630; therefore, the Agriculture Discipline is mapped.
-
NLMCallNum value is within the range of W82 to W83.1; therefore, the Biomedical Engineering Discipline is mapped.
Disciplines Mapped in CDI
The Summon service currently supports 59 Disciplines and uses the HILCC taxonomy.
If there are additional Disciplines based on the HILCC standard that you want to see used in CDI, please let us know by using the Support Portal option located near the top of this page.
Hundreds of millions of items in CDI have Disciplines assigned; however, not all content has yet been assigned a Discipline. Newspaper articles do not have Disciplines assigned, nor do items of other content types that do not associate with a Discipline via the mapping methods used. As new ways of mapping Disciplines are developed, additional content will be assigned Disciplines.
