Encyclopaedia Of Classification And Communication

Library classification of a piece of work consists of two steps. Firstly. the" abruptness" of the material is ascertained. Next, a call number(essentially a book's address), based on the basification 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.
