Examples

Examples of values for this property, and an explanation of the reasoning for the values.

Value	Explanation
621.3678	The subject of the Landmap collection. The term represents Remote sensing technology. No other Dewey terms are relevant.
025.524	Dewey terms for the JISC Information Environment Service Registry collection. 025.524 is the term for Information search and retrieval and 302.231 is for Electronic resources.
302.231
538	Subject terms for the CrossFire collection. The terms represent Magnetism, Physical chemistry, Inorganic chemistry, Organic chemistry respectively. A maximum of three terms that are children of another term have been used: 541, 546 and 547 are children of 540. If more than three terms had been relevant under 540, then 540 would have been used instead of the child terms.
541
546
547
330	Terms used for the National Statistics Time Series Data collection. The terms stand for Economics, Commerce (Trade), International commerce (Foreign trade) and Accounting. Many terms under 330 are relevant, so 330 has been used.

382
657
000	Subjects for the Copac collection. Copac is a multidisciplinary collection, and covers all subjects. Hence all of the top level subject terms from Dewey are used, as the intellectual content of the collection covers all of these subject areas.

Guidelines

Values for this property are defined by Dewey Decimal Classification (DDC, or Dewey). Dewey is a library classification system and may only be used under licence. Organisations with a licence for Dewey should use one or more full Dewey terms. Organisations without a licence to Dewey should enter one or more terms from the DDC Summaries; these have a separate licence agreement. If no Dewey terms are entered then one or more terms will be assigned by the IESR Content Manager.

Subject Indexing Policy

The set of terms used under each controlled vocabulary must describe the collection fully.

Do not use term(s) that only describe the type, form, spatial coverage or temporal coverage of the collection, as the term(s) will not describe the subject of the collection. For example, if the collection is a database, it should not be indexed with the LCSH term Databases, as this describes the type of the collection only, not the subject of the intellectual content. The type, or form, of the collection is indexed separately under Collection Type and Item Type. Spatial and temporal coverage are indexed separately under Spatial and Temporal. The exception to this rule is Subject (LCSH). LCSH terms that include this information as subdivisions may be used, for example: History--20th century.

Use up to three related terms which are under the same broader term. If more than three terms in the same tree are needed then use the broader term instead. The depth of analysis is at your discretion, but it is suggested that five or more subject terms are entered, unless the collection's subject coverage is very specific.

Multidisciplinary resources may be indexed using the highest level subject terms in the chosen controlled vocabulary. Do not use terms that only describe the type or form of the collection. The set of terms used must fully describe the collection. For example, a multidisciplinary collection might be indexed with the following top-level terms from Dewey:

• 000
• 100
• 200
• 300
• 400
• 500
• 600
• 700
• 800
• 900

as the intellectual content of the collection covers all of these subject areas.

If the collection is a catalogue, index or hierarchical finding aid, then the term(s) used for Subject describe the intellectual content of the collection the catalogue describes (not the intellectual content of the catalogue, index or hierarchical finding aid records themselves). For example, the Copac collection is a catalogue. Subject describes the intellectual content of the books, manuscripts etc described in Copac.
