Book Index Entries
Book Index Entries are specific Added Word Entries provided for a document. These entries are given under the names of authors, editors, translators etc., under the name of series and in certain cases under the title.
In the case of titles, added entries are given in the Classified Catalogue as per CCC only if the title of the book
1) is fanciful
2) contains a proper noun or
3) is treated in usage as a proper noun
Further, the title (a) should not have been used as the Heading of the Main Entry; or (b) it is not as such eligible to be used as the Main Heading of a Class Index Entry of the book. These two conditions are to avoid duplication of entries.
