Added Entries:

As mentioned earlier, Added Entries are made using the information given in the Main Entry. The number and  type of Added Entries required will vary according to the document. The cataloguer will  decide about them and make necessary indications on the Process Slip.  If Unit Cards are to  be used, necessary copies of the Main Card should be taken with the help of the Card Copier or got typewritten. Appropriate headings are  then entered oil the top of the Added Entries. In the case of a handwritten catalogue, when duplicating facilities are not available, added entries can be prepared even with the minimum information as the catalogue code may prescribe. 

Tracing: After making the Main Entry and the Added Entries the cataloguer should write the tracing on the back of the Main Card.  The tracing will be an indication about the Added Entries made for each document.  This will be  a guide when the entire set of cards relating to a book is to be pulled out of the catalogue either for the purpose of correction, consolidation or when the book is to be finally withdrawn from the stock. 

Shelf-list Card: It is usual to maintain in libraries a Shelf-list  in card form. This contains a card each for a volume and is arranged parallel to the arrangement of the documents in the library shelves. A card in the Shelf-list will be either a duplicate of the Main Card or an abridged form  of  the Main Entry. The  essential pieces of information on a Shelf-list Card are the Call Number, Author, Title and Accession Number. The purpose of the Shelf-list is to enable convenient stock verification. It is the duty of the Technical Department to maintain the Shelf-list. The cataloguer must therefore prepare the Shelf-list Card for each volume of a document processed.
