- Field Detail
  - keywords
```
public Hashtable keywords
```
    The keywords are usually (but not limited to) one word long. They are not controlled by any vocabulary.
  - subjectHeadings
```
public Hashtable subjectHeadings
```
    The subject headings usually come from standard lists such as Sears List of Subject Headings, or Library of Congress Subject Headings (LCSH). This specification does not specify what list to use but implementors are advised to provide a controlled vocabulary for the list that is used, and to specify the source of subject headings in subjectHeadingsSource field. The name of such vocabulary should be equal to BibRefSupport.SUBJECT_HEADINGS.
  - subjectHeadingsSource
```
public String subjectHeadingsSource
```
    The source of subject headings. For example:
    
    SEARS
    for Sears List of Subject Headings
    LCSH
    for Library of Congress Subject Headings (LCSH)
    MeSH
    for MEDLINE Mesh Terms
  - codes
```
public Hashtable codes
```
    Classification code (call number) is usually either Dewey decimal or Congress classification. But this specification does not prescribe it.
    
    Note that the classification codes are unique (unlike some subject headings). Therefore, they can be even expressed as identifiers using the same notation as used for the citation identifiers.
