Categorised classes and subjects display
Using the standard Subjects and Classmarks fields you can display more than one subject and more than one classmark for a Title record, with each one showing a different Type. The subject headings in a Title record may appear like this for example:
| Housing | Thesaurus |
| Yorkshire and the Humber: Bradford- Housing action areas | Geog. Trace |
However, for some implementations it may be preferable to display the different types of subject headings and classmarks in separate fields on the Title screen. Using categorised classes and subjects display enables you to do this. For example you may have separate subject fields in the Titles screen for Topics, Chemicals, Places and so on. When you search to add data in these fields, the search only displays data relevant to that Subject Type. In the OPAC it is also possible to display the list of data in each type more distinctly.
Set up categorised classes and subjects display
Using Layout Manager: in addition to the standard subject and classmark attributes in the Titles layout, 9 separate subject attributes (Subjects (Type 1) – Subjects (Type 9)) and 9 separate classmark attributes (Classmarks (Type 1) – Classmarks (Type 9)) are included.
The standard subject and classmark attributes are set at Subjects (Type 0) and Classmarks (Type 0).
To use the additional fields for subjects and classes, the system manager needs to:
- add one or more of the attributes to the Titles layout using Layout Manager, e.g. Subjects (Type 1) or Classmarks (Type 1)
- rebuild the configuration data in OLIB Web
Subject type and classification scheme reference data
To display data in one of the new attributes edit the Subject Type and Class Scheme in Cataloguing Reference Data:
Subject type
- Go to Subject Types.
- Search for the subject type that you would like to be displayed in the new field.
- In the Subject Type Code enter e.g. 1, depending on which attribute was added to the Titles layout.
Class scheme
- Go to Classmark Schemas.
- Search for the scheme that you would like to be displayed in the new field.
- In the Class Type Code enter e.g. 1, depending on which attribute was added to the Titles layout.
If the Type Code field is blank or if it is set to 0, the subject/classmark will be displayed in the respective Type 0 attribute; if the Type Code field is set to 1, the subject/classmark will be displayed in the respective Type 1 attribute, and so on.
Note: until otherwise configured, all subjects and classmarks continue to be displayed in the standard subject/classmark (Type 0) attribute.
Add combo fields in layout manager
Optionally, the system manager can add up to 10 "combo" fields in Layout Manager, one for each of the Subject Type codes. This allows the cataloguer to quickly enter new subject terms for the title. They include a data entry field and an associated button. These can be placed above the relevant Subjects (Type n) list boxes on the titles layout to make things simpler for the cataloguer.
The drop down lists for these fields include the subjects with a subject type that has been allocated to the respective code. For example:
Subject Type
| Key ID | BULL |
| Short Description | Bulletin |
| Long Description | Bulletin |
| Subject Type Code | 1 |
Here, the Bulletin Subject Type has been allocated a Subject Type Code 1.
The Layout Manager attributes can be added to the title layout next to the corresponding subject list field, e.g:
| Bulletin Heading | Subjects (Type 1) (titlesubjs_1) |
| Bulletin Code | Subject 1 Pick-List (ti_subj1_combo) |
Staff can quickly add a subject to a title using the drop down list (without having to open the dependent search, search for the subject to be added and click Insert).
Use the new attributes
When the above set up is completed, the subject and classmark fields in the Titles domain are visible. Click Search on the chosen Type, this opens up the relevant search for the attribute's Type.
For Subjects, if the combo fields were added as above, quickly add a subject to a title using the drop down list.
Search using the new attributes
It is possible to search subject headings and classmarks specifically on these attributes. For example
- Go to the Cataloguing>Subject Headings domain.
- Click Other Searches to choose from:
Subject Heading Search (incl. Preferred Terms) (Type 0)
Subject Heading Search (incl. Preferred Terms) (Type 1)
Subject Heading Search (incl. Preferred Terms) (Type 2)
Subject Heading Search (incl. Preferred Terms) (Type 3)
Subject Heading Search (incl. Preferred Terms) (Type 4)
Subject Heading Search (incl. Preferred Terms) (Type 5)
Subject Heading Search (incl. Preferred Terms) (Type 6)
Subject Heading Search (incl. Preferred Terms) (Type 7)
Subject Heading Search (incl. Preferred Terms) (Type 8)
Subject Heading Search (incl. Preferred Terms) (Type 9)
A similar range of classmark searches also exist in the Classes domain search.
