Library classification is a work consists of two steps. Firstly, the "about ness" of the material is ascertained. Next, a call number (essentially a book's address) based on the classification system in use at the particular library will be assigned to the work using the notation of the system. It is important to note that unlike subject heading or thesauri where multiple terms can be assigned to the same work, in library classification systems, each work can only be placed in one class. This is due to shelving purposes: A book can have only one physical place. However, in classified catalogues one may have main entries as well as added entries. The book contains the cataloging and classification skills of library and information science graduates which is centered on assessing the cataloging and classification skills of academic and school librarians in three areas namely, descriptive cataloging, subject analysis and classification. This book contains various issues related with the theme of library and information science, which may be useful for the entire library and information science professionals as well as other academicians.
