Who owns all the copyrights of DDC?
The copyrights to the Dewey Decimal Classification (DDC) system are owned by the Online Computer Library Center (OCLC), which is a nonprofit organization based in Dublin, Ohio. OCLC is an international consortium of libraries that provides a range of services and resources to libraries and their users, including the DDC system.
OCLC has owned the copyrights to the DDC system since 1988, when it acquired the rights from the American Library Association (ALA), which had previously been the copyright holder for the DDC system. OCLC is responsible for maintaining and updating the DDC system, and it publishes both print and digital versions of the classification system. The digital version of the DDC system, known as Web Dewey or E-DDC, is available online and is used by libraries and researchers around the world to classify and organize materials according to subject matter.

What is the basic plan of DDC?
The basic plan of the Dewey Decimal Classification (DDC) system is a hierarchical structure that is based on a decimal numbering system. The system is divided into 10 main classes, which are arranged according to subject matter. Each main class is further divided into subclasses and categories, and each subclass and category is further divided into more specific subcategories and sub-subcategories.
The main classes of the DDC system are:
- Philosophy and psychology
- Religion
- Social sciences
- Language
- Pure science
- Technology
- Arts and recreation
- Literature
- History and geography
- Miscellaneous
Each main class is assigned a unique decimal number, and the subclasses and categories within each main class are assigned decimal numbers that are based on the main class number. For example, the subclass “Mathematics” within the main class “Pure science” (class 5) is represented by the decimal number “510,” while the category “Trigonometry” within that subclass is represented by the decimal number “517.”
In addition to the decimal numbering system, the DDC system also includes a system of captions and notation schedules that provide more detailed information about the meaning and content of each class, category, and subcategory. These tools are used in conjunction with the decimal numbering system to create a comprehensive and detailed classification system that is used to organize and classify books and other materials according to subject matter in libraries.

DDC is based on what classification system?ڈی ڈی سی کس درجہ بندی کے نظام پر مبنی ہے؟
The Dewey Decimal Classification (DDC) system is based on a decimal numbering system, in which each class, category, and subcategory is assigned a unique decimal number. The system is hierarchical, with 10 main classes at the top and more specific categories and subcategories below them. The main classes are arranged according to subject matter, and each subclass and category is further divided and refined according to specific topics or themes.
The DDC system is an artificial classification system, which means that it is not based on the inherent characteristics or traits of the materials being classified, but rather on criteria that have been chosen by the person or group creating the classification system. In the case of the DDC, the criteria for classification are based on subject matter, and the system is designed to be flexible and adaptable so that it can be used to classify a wide range of materials.
The DDC system is widely used in libraries around the world to organize and classify books and other materials according to subject matter, and it is considered to be an essential tool for organizing and accessing information in libraries.

Why and how Melvil Dewey thought to develop his own classification system?کیوں اور کیسے میلویل ڈیوی نے اپنا درجہ بندی کا نظام تیار کرنے کا سوچا؟
Melvil Dewey developed the Dewey Decimal Classification (DDC) system as a way to organize and classify the books in the Amherst College Library, where he was working as a librarian in the late 19th century. At the time, library classification systems were generally based on a hierarchical structure, with broad main classes at the top and more specific subclasses and categories below them. However, Dewey felt that these systems were too broad and general, and he believed that there was a need for a more detailed and specific classification system that would allow for greater precision and accuracy in organizing and accessing library materials.
To develop his own classification system, Dewey began by studying the existing systems that were in use at the time, and he drew on his own knowledge and experience as a librarian to identify the strengths and weaknesses of each system. He then used this information to create a new classification system that was based on a decimal numbering system, with 10 main classes at the top and more specific categories and subcategories below them.
Dewey’s classification system was designed to be flexible and adaptable, and he believed that it would be more efficient and effective than the existing systems for organizing and accessing library materials. He published the first edition of the DDC system in 1876, and it has since become one of the most widely used library classification systems in the world.
Under what title the DDC first time published?
The first edition of the Dewey Decimal Classification (DDC) system was published in 1876 under the title “A Classification and Subject Index for Cataloguing and Arranging the Books and Pamphlets of a Library.” This original edition of the DDC was relatively small, with just 10 main classes and a few hundred subcategories.
Since its initial publication, the DDC system has undergone numerous revisions and updates, and it has grown to become a comprehensive classification system that covers a wide range of subjects and topics. Today, the DDC is published by the Online Computer Library Center (OCLC), and it is used by libraries around the world to organize and classify books and other materials according to subject matter.

Explain ordinary classification?عام درجہ بندی کی وضاحت کریں؟
Classification can refer to the process of organizing and grouping things into categories based on shared characteristics or attributes, and it is used in a variety of fields, including biology, library science, and information science.
In the context of library science, classification refers to the organization of books and other materials according to a set of standardized rules and guidelines, such as the Dewey Decimal Classification system or the Library of Congress Classification system. These systems use a specific set of numbers or letters to represent different subjects or categories, and the books in a library are assigned call numbers based on their classification.
If you are asking about a specific type of classification, it would be helpful to provide more context or clarify the term you are using.
