    Summon: Disciplines in the Summon Index

    • Product: Summon

    How is content mapped to Disciplines in the Summon Index?

    Libraries using the legacy Summon interface should jump here. If you are not sure if your library uses the legacy or the 2.0 interface, compare your Summon search box to the legacy and 2.0 search boxes displayed in the Summon 2.0 overview.

    How Disciplines Work in Summon 2.0

    The Summon service provides your patrons the ability to narrow a search based on the Discipline facet. This document explains how Disciplines are mapped in the Summon index and which Disciplines are available.
    This page contains two sections:

    Discipline Mapping in the Summon Index

    Content in the Summon index comes from several sources: providers, institutional repositories, and your catalog. Using information from all of the sources, the Summon service maps Disciplines via the Subject Term and Call Number fields in the Summon index. Disciplines are mapped at the individual item-level, not at the broad database level. Journal articles, along with items from many other content types in Summon, have one or more Disciplines mapped to them.
    As new content is indexed in Summon, it will be assigned to a Discipline, as long there is an existing Discipline match.

    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 the Summon Index.

    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 the Summon Index

    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 the Summon index, please let us know by using the Support Portal option located near the top of this page.
    Hundreds of millions of items in the Summon index 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.
    We support the following Disciplines:
    Agriculture
    Anatomy & Physiology
    Anthropology
    Applied Sciences
    Architecture
    Astronomy & Astrophysics
    Biology
    Botany
    Business

    How Disciplines Work in the Legacy Summon Interface

    The Summon service provides your patrons the ability to scope searches based on Disciplines. This document explains how Disciplines are mapped in the Summon index and which Disciplines are available.
    Discipline-scoped searching is only available in search boxes and search widgets, so that you, and we, can evaluate how effective Disciplines are for your patrons and to avoid confusion with existing facets such as Subject Terms. We look forward to your feedback.
