SUMMARY OF IMPORTANT ARTICLES
  • Library Classification - Classification or Library Classification or Book Classification or Bibliographic Classification is the process of arranging, grouping, coding, and organizing books and other library materials (e.g. serials, sound recordings, moving images, cartographic materials, manuscripts, computer files, e-resources etc.) on shelves or entries of a catalog, bibliography, and index according to their subject in a systematic, logical, and helpful order by way of assigning them call numbers using a library classification system, so that users can find them as quickly and easily as possible. Call number consists of a class number providing class designation, a book number providing author representation, and a collection number denoting the collection to which it belongs. In ordinary classification, we deal with the arrangement of ideas and the objects in a systematic order. But in library classification we are concerned with documents, and the aim is to arrange these in the most helpful and permanent order. Similar to knowledge classification systems, bibliographic classification systems group entities that are similar and related together typically arranged in a hierarchical tree type structure (assuming non-faceted system; a faceted classification system allows the assignment of multiple classifications to an object, enabling the classifications to be ordered in multiple ways). It requires a detailed scheme of classification in which knowledge is divided into broad areas, which are again subdivided into subjects or main classes. Main classes are further divided into sub-classes, and sub-classes are divided into and divisions and so on. In this way classification proceeds from the general to the specific dividing and categorizing concepts into logically hierarchical classes based on the characteristics they have in common and those that distinguish them. Levels of hierarchy in the classification schedules are indicated by indentions. Each subject, classes, sub-classes, and its divisions are represented by a system of numerals or letters or a combination of both called Notation. It is this notation that helps in the arrangement of documents on the shelves. Classification provides a logical approach to the arrangement of documentary materials ... ... ...
  • Library of Congress Classification - The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It was developed in the late nineteenth and early twentieth centuries to organize and arrange the book collections of the Library of Congress. Over the course of the twentieth century, the system was adopted for use by other libraries as well, especially large academic libraries in the United States. It is currently one of the most widely used library classification systems in the world. The Library's Policy and Standards Division maintains and develops the system¹. In recent decades, as the Library of Congress made its records available electronically through its online catalog, more libraries have adopted LCC for both subject cataloging as well as shelflisting ... ... ...
  • Assigned Indexing - If the terms are selected from the title or the text of a document and used without any alteration as index terms, then this is referred to as natural language indexing or derived indexing. If however, the selected terms are translated or encoded into authorized terms by the help of a prescribed list, then the indexing language becomes controlled or artificial. This process is called Assigned Indexing ... ... ...
  • Chain Indexing - Chain Indexing or Chain Procedure is a mechanical method to derive subject index entries or subject headings from the class number of the document. It was developed by Dr. S.R. Ranganathan. He first mentioned this in his book “Theory of Library Catalogue” in 1938. In Chain Procedure, the indexer or cataloguer is supposed to start from where the classifier has left. No duplication of work is to be done. He/she has to derive subject headings or class index entries from the digit by digit interpretation of the class number of the document in the reverse direction, to provide the alphabetical approach to the subject of the document. Ranganathan designed this new method of deriving verbal subject heading in 1934 to provide the subject approach to documents through the alphabetical part of a classified catalogue ... ... ...
