Classified Catalogue Code (CCC) Overview
The Classified Catalogue Code (CCC) is a pioneering set of rules for cataloguing documents in libraries, developed by the renowned Indian librarian Dr. S.R. Ranganathan. Its primary purpose is to organize library materials into a "classified catalogue," which arranges documents systematically by their subject using a classification scheme, most notably the Colon Classification (CC), also developed by Ranganathan.
A classified catalogue is highly effective for subject-based searches and typically comprises two main sections:
- Classified Part: This section arranges entries strictly by their class numbers (subjects).
- Alphabetical Index Part: This provides alphabetical access points through authors, titles, series, and subject terms (which link to class numbers).
Specific Added Class Number Entry Explained
In a classified catalogue, while each document has a primary subject represented by its main class number, it often contains information relevant to other subjects as well. To ensure that users can discover all pertinent materials, even when they are not the primary subject of a document, the CCC includes provisions for 'added entries'.
A 'specific added class number entry' is precisely what it sounds like: an additional entry created for a document under a class number that is not its main class number but represents a significant, related subject or aspect covered within the document. This entry serves to direct the user from that related subject's class number to the actual location of the document.
Cross Reference Entry in CCC
According to the Classified Catalogue Code, the definition of a 'specific added class number entry' directly corresponds to a Cross Reference Entry. A Cross Reference Entry is a fundamental component of the classified catalogue that guides users from one class number or heading to another related class number where more information or relevant documents can be found.
For instance, if a book primarily classified under 'Indian History' (e.g., class number V44) also contains substantial content on 'Indian Painting' (e.g., class number NA44), a Cross Reference Entry would be made from the class number for 'Indian Painting' to the class number for 'Indian History' where the book is located. This entry effectively acts as the 'specific added class number entry' for 'Indian Painting', ensuring that users looking for books on Indian painting are directed to this relevant source.
Types of Entries in Classified Catalogue Code (CCC)
The CCC outlines various types of entries, each serving a specific purpose in providing comprehensive access to library resources:
| Entry Type | Purpose |
|---|---|
| Main Entry | The complete bibliographic record for a document, providing all necessary details and its main class number. |
| Cross Reference Entry | Refers users from one class number (or a specific heading) to another related class number where relevant documents are found. This includes 'specific added class number entries'. |
| Book Index Entry | Alphabetical entries for authors, joint authors, titles, series, and other collaborating entities, guiding users to the main entry. |
| Class Index Entry | Alphabetical entries for the subject headings that correspond to the class numbers used in the classified part, enabling alphabetical subject access. |
| Cross Reference Index Entry | Alphabetical entries that refer from one index term to another, or from a broader term to a specific one, or from a synonymous term to the preferred term in the index. |
Thus, the concept of a 'specific added class number entry' is perfectly embodied by the function of a Cross Reference Entry within the Classified Catalogue Code, ensuring maximal discoverability of library materials by subject.
