Classification Overview and Types

Arranging things in a particular order or into categories based on their similarities.

The practice of grouping information materials of the same subject together in a library.

The process of categorizing knowledge into a hierarchical structure, starting with broad categories and becoming more specific.

A widely used classification system that divides knowledge into 10 main classes, represented by numbers from 000 to 900.

The 10 main classes in the Dewey Decimal Classification represent broad categories of knowledge, such as science, history, and language.

Each of the 10 main classes in the Dewey Decimal Classification is further divided into 10 subclasses, allowing for more specific categories.

The Dewey Decimal Classification system provides a structured and systematic method for organizing library materials, making it easier for users to find resources on specific topics.

The Dewey Decimal Classification helps users find materials by providing subject access, making collections browsable, and facilitating organization and retrieval.

The Dewey Decimal Classification (DDC) system uses a unique numerical notation system, with digits indicating the level of specificity in the classification. The higher the number of digits, the more specific the topic.

The DDC hierarchy signifies the relationships between different subjects, where broader subjects encompass narrower ones. This hierarchical structure is represented by the length of the notation. Longer notations indicate more specific subjects, while shorter ones indicate broader categories.

In the DDC hierarchy, "Dogs" and "Cats" are considered more specific than "Animal husbandry" because they represent a more specific category within the broader subject of animal husbandry.

The DDC system uses notations to represent each subject, providing a unique code to identify and organize books and materials. For example, the notation "636.7" represents the topic of "Dogs."

A call number is a unique identifier assigned to each item in a library, consisting of a class number (DDC code) and a 3-letter code derived from the author's name or the title of the book. These numbers are typically found on the spine of the book and help librarians locate and shelve books efficiently.

A system used to organize and locate library materials. It involves assigning unique call numbers to each item, based on its subject, author, and format.

The first part of a call number, representing the Dewey Decimal Classification (DDC) number, which categorizes the subject matter of the resource.

The letters following the DDC number in a call number, which usually represent the author's last name, or the title of the book if no author is identified.

A prefix added to a call number to indicate the format of the library resource. Examples include J for Journal, R for Reference, A for Article, G for Government document, etc.

A specific order followed when shelving books in a library. Books are arranged from left to right on the shelf, based on their call numbers. This means the numerical part is sorted first, then the alphabetical part.

A collection of books that are all categorized under the same Dewey Decimal Classification number, such as 500 for Science, 600 for Technology, etc.

Books are typically arranged on library shelves with their spines facing out, helping users to easily read the call number and identify the book.

The process of putting books back in their proper place on the shelves in the library, ensuring they are arranged according to the call number system.
