Specificity : The system should allow for a precise and specific classification of materials. Flexibility : The system should be flexible enough to accommodate changes and new additions to the collection.

Accessibility : The system should be designed to facilitate easy retrieval and use of materials by library users. User-centered : The classification system should be designed with the needs of library users in mind, rather than the preferences of library staff or administrators. Overall, the principles of library classification are aimed at making library materials more easily accessible and usable for library users, while also facilitating efficient management and organization of the library collection.

Library classification is the process of organizing library resources systematically. The principles of library classification include:. Subject Approach : If classification helps in the use of books, a method of systematic arrangement is adopted, whether it is logical or not. Extension and Intention : The classification should be based on the extension and intention of the subject.

Inductive and Deductive Nature of Classification : The classification should be based on both inductive and deductive methods. Aristotelian Pattern : The classification should be based on the Aristotelian pattern of division. Hierarchical Structure of Classification : The classification should be based on a hierarchical structure. Class works according to their subject matter.

Topic vs. Unless instructions to the contrary are printed in the schedules, class a work by its specific subject, not by its form under a broader topic. Within a given topical area, class by subject, ignoring form unless form captions have been established under the subject. If no number for the specific form of the work being cataloged has been established in the schedules under the subject, see F , sec.

Within a given topical area, if a choice must be made between classing by specific subject and classing by place, prefer classification by the subject, unless instructions to the contrary exist or unless precedent, as reflected in the shelflist, clearly indicates otherwise. If no clear precedent exists, record any decision to class by place rather than by subject by adding notes of the following type to the schedule:.

The purpose of the classification system is to shelve items on the same topic together, allowing researchers to browse areas of the collection relevant to their topics.

This system is used by the Library of Congress and many academic and research libraries in the United States. Analytico-synthetic classification schemes combine the analytical approach of dividing subjects into smaller components with the synthetic approach of creating a hierarchical structure. Faceted classification schemes organize subjects based on multiple facets or characteristics, allowing for flexible and precise classification.

Enumerative Classification Schemes: An enumerative Library classification scheme is a scheme where all the possible classes are enumerated according to specific characteristics. There is a top-down approach whereby a series of subordinate classes are produced and where both simple and complex subjects are listed. The advantage of this scheme is that the structure of the scheme is shown by the notation as far as practicable.

Users can easily find the coordinate and subordinate classes and can make a map of the subject. The disadvantage is that it is difficult to accommodate new subjects, and frequent revisions may be required. An enumerative classification scheme, in some cases, displays hierarchical structures of notation. The basic tenet of this scheme is that all the possible subjects and topics are listed along with a predefined class number.

Therefore, the classifier does not have to create any class number such as Dewey Decimal Classification. Analytico-Synthetic Classification Scheme: Analytico-Synthetic Library classification schemes resolve some of the problems of enumerative classification schemes. The concept behind this scheme is that the subject of a given document will be divided into its constituent elements.

Then, the classification scheme will be used to find notations for each element, which will then be combined according to the prescribed rules to prepare the final class number. This scheme overcomes the two major problems of enumerative classification schemes by providing various tables, specific notational symbols, and rules; they avoid the necessity for a long list of classes and thus produce a smaller classification scheme in size; they also provide flexibility to users as specific numbers can be built, and the availability of a specific subject does not restrict the classifier.

Faceted Classification Scheme: A faceted classification scheme is on the other extreme of the scale.
