In order for SDI to function, some or all Subject headings in the database need to be flagged as SDI subjects. Choose from 3 different ways to achieve this:
When entering Subjects, assign them to the predefined Subject Type SDI Term. All subjects of this type will be flagged as SDI terms. Potentially the user may have a very long list of subjects to choose from however.
All Subjects belonging to the Subject Type, will be available for SDI. It allows the end user to have a succinct list of Subjects, but the cataloguer must ensure that a subject of this type is added to each Title.
Simply add the SDI subject headings in the Subject Headings domain, using one of the SDI subject types. Subjects with a subject type which is flagged as an SDI Type will be included in the list of available SDI subject headings when the user edits his/her SDI profile in the OPAC.
Alternatively, or in addition, you can use the Subject Headings record itself to indicate whether a subject should be treated as an SDI subject. This is particularly effective when used with a structured Thesaurus.
Subjects with this flag will also be treated as SDI subject headings.
Note: You can set this to Yes for any subjects that don't have one of the SDI subject types.
