Element Name

Subject/Keyword

 

Definition

The subjects or topics that succinctly describe the content of the resource.

 

Where Can the Subject Information be Found?

In many cases, the item must be read/examined to find subjects and keywords but they may come from:

Item Types Information Sources
For text
  • titles
  • abstracts
  • tables of contents
  • section/chapter headings
  • text
For images
  • bottom or back of a photograph
  • visible items (people surroundings, objects, etc.)
  • illustrations
For maps
  • statement in a caption
  • notes around the outside of the map
  • geographic area and time period of the map
For music scores
  • title page
  • table of contents
  • lyrics
For videos
  • label on disc
  • container cover
For sound files
  • information on disc/cassette
  • container information
For computer files
  • title page/screen
  • text of document

 

In some cases subjects may come from accompanying or supplementary information.

How Should the Subject be Filled in?

General Subject/Keyword Rules

  • Information in the subject/keyword field should describe what the content is 'about'
    • Subjects/keywords answer questions like: who, what, where, and when

  • Choose as many terms as necessary to capture subject content:
    • Two subjects are required, but an average of five subject/keyword entries is recommended (number varies depending on content)
    • Avoid terms too general to describe a particular item
    • Only include geographic subjects when the particular place is important to the subject content
    • The use of controlled vocabularies is not required (except UNTL-BS terms for items in the Portal)

  • Proper names can be subjects (including persons, places, titles, etc.)

  • Follow the general formatting rules for consistency:
    • Use appropriate capitalization, punctuation, etc. depending on the type of subject
    • Terms from controlled vocabularies must use the exact formatting prescribed by the source
    • Choose the appropriate subject type from the controlled vocabulary

 

Keywords and Phrases (KWD)

 

Formatting Keywords

Guideline Example
  • Add informal keywords as needed to help users locate the resource
  • It is not necessary to repeat terms from controlled vocabularies as keywords
greeting cards
  • Keywords should be lowercase
  • Only capitalize proper nouns

  • Use punctuation when applicable
  • If needed, include multiple versions with different spacing/punctuation
  • Do not add quotation marks to titles
long-range planning

  • Use plural forms of keywords
cadastral maps
  • The singular form of a keyword can be used when there is no reasonable plural

  • If the keyword's plural is formed irregularly, the singular and plural forms can both be added as separate keywords

knives
  • When referring to a company, organization, school, military installation, etc., the abbreviated version of the name can be used, but the full name must appear at least once in the record (preferably in the content description or as a keyword).
  • If it seems important, both the full name and abbreviated version(s) can be included as keywords
Description: Postcard of buildings at Ft. McIntosh.
Keyword: Fort McIntosh

UNT
University of North Texas

 

Assigning Keywords

  • When assigning keywords, keep in mind that they should help users find the item you're describing and also help the item be found with other, similar items.
  • Follow all formatting guidelines (e.g., make keywords lowercase and plural)
  • Here are some suggestions:
Guideline Instead of: Consider:
  • Keep keywords short; break up long, complex phrases

  • 'Named persons' refers to people who are significant in some way to the content of the item (see below for clarification)

  • Only include names as 'named persons' if a surname is known
  • If only a first name, first and middle names, or nickname is known:
    • Use the name in the content description (if relevant)
    • Use the name in the title (if relevant)
  • All names should have the same format:
Guideline Example
  • Invert the name (Last, First Middle)
Lott, Leanna Ivory
  • Use any known part of the name including initials if the full name is unknown
Thompson, J. D.
  • Include additional names as middle names
Williams, Mary Deline Xenia Buchanan
  • Names that are hyphenated or have multiple parts are all considered 'last names'
Smith-Jones, John

UNT Libraries Browse Subjects (UNTL-BS)

 

  • UNTL-BS are used for records in The Portal to Texas History
  • For records about Portal objects, include at least one subject (preferably more) from the UNT Libraries Browse Structure
  • Choose as many appropriate terms as necessary from the UNTL-BS list
Guideline Example
  • Terms in UNT browse subjects are separated by a single dash and spaces (Term - Term)
Sports and Recreation - Riding - Bulls
  • For subject strings that have several levels, it is not necessary to include each part separately
  • Only use the most specific and relevant string(s)
Not: 'Social Life and Customs' and
'Social Life and Customs - Customs' and
'Social Life and Customs - Customs - Weddings'
Social Life and Customs - Customs - Weddings
  • Only use UNTL-BS terms starting with "Places" if the place itself is important to the subject of the item (e.g., maps, landscape photos, travel books)
  • Consider how place terms will overlap with coverage places:
    • For some items, a location associated with the item will be a coverage place but not a subject (e.g., portraits, event programs, etc.)
    • The UNTL-BS includes place names that cannot be used as coverage locations, such as (U.S. regions and historic locations)
Places - United States - Texas - Travis County - Austin

Places - United States - Midwestern Region

Places - Republic of Texas

 

Note: Additional subjects are added to the UNTL-BS whenever there are enough items to warrant it, so the number of subjects is consistently growing.  If you would like to suggest a new subject, please notify Hannah Tarver (hannah.tarver@unt.edu).

 

Subjects from Other Established Thesauri or Controlled Vocabularies

 

  • The UNT Libraries schema supports a number of controlled vocabularies and encourages the use of any readily-available subjects (e.g., from established thesauri or discipline-related word lists) that would be helpful for users
  • Editors are never required to include terms from external controlled vocabularies
  • When included, the vocabulary used should be identified for each term
  • If the name of the controlled vocabulary is not in the list, choose "other" and notify the metadata administrators

 

Library of Congress Subject Headings (LCSH)

 

Guideline Example
  • Subject strings must be formulated and formatted according to Library of Congress rules
    • Terms in Library of Congress subjects are separated by a double dash (Term -- Term)
    • Strings must end with a period unless there is a close parenthesis or open-ended date at the end
Bee culture -- Equipment and supplies.

Capote, Truman, 1924-
  • If the resource has previously been described in a library catalog subject fields can be taken from the catalog record

Comments

  • Since the "subject and keywords" element may describe both what the object is about and the format in some cases, subject-related information may be repeated in other elements:
    • An image with a Resource Type "Photograph" could have a more specific subject term such as "cabinet cards", "ambrotypes", or "panoramic photos"
    • To describe a resource, such as an autobiography, that is about its creator, place the creator's name in both the subject/keyword element and the Creator element.
    • Although geographic terms are normally handled by the Coverage (Place Name) element, subject fields could include geographic terms as well.
