The practice of classifying A library classification is associated with library (descriptive) cataloging under the rubric of  cataloging and classification , sometimes grouped together as  technical services . The library professional who engages in the process of cataloging and classifying library materials is called a  cataloger  or  catalog librarian . Library classification systems are one of the two tools used to facilitate  subject access . The other consists of alphabetical indexing languages such as Thesauri and Subject Headings systems. Library classification of a piece of work consists of two steps. Firstly, the "aboutness" 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...

In  library and information science ,  cataloging  (or  cataloguing ) is the process of creating  metadata  representing information  resources , such as books, sound recordings, moving images, etc. Since the 1970s these metadata are in  machine-readable form  and are indexed by information retrieval tools, such as  bibliographic databases  or  search engines . While typically the cataloging process results in the production of  library catalogs , it also produces other types of discovery tools for  documents  and collections. Bibliographic control  provides the philosophical basis of cataloging, defining the rules for sufficiently describing information resources to enable users to find and select the most appropriate resource. A  cataloger  is an individual responsible for the processes of description, subject analysis, classification, and  authority control  of library materials ...

Colon Classification is one of the most systematic schemes of Library Classifications used in many libraries in India and a few libraries abroad as well. This was devised by the late Dr. S.R. Ranganathan. He found the existing scheme of library classification unable to cope with the multidimensional dynamic growth of universe of subjects. Colon Classification proceeds in a different manner in spite of enumerating all possible subjects and their subdivisions, it analyses the subject in its various components and places them under five fundamental categories known as personality, matter, energy, space and time. To connect or to synthesize the various components of a subject, different connection symbols have been provided. Readymade class numbers are also available, but to build a class number, one has to analyze and pick up the possible isolates belonging to different fundamental categories which are then put together with the help appropriate connecting symbols. Colon Classifi...
