What is a main class in classification system?درجہ بندی کے نظام میں ایک اہم کلاس کیا ہے؟

Leave a Comment / LIS Studies, Questions & Answer / / / , ,

In a library classification system, a main class is a broad category that is used to group together books and other materials that have similar subject matter or content. These main classes are usually organized according to a hierarchical system, with the main classes at the top and more specific subclasses below them.

For example, in the Dewey Decimal Classification system, which is a commonly used library classification system, the main classes are organized into 10 broad categories:

  1. Philosophy and psychology
  2. Religion
  3. Social sciences
  4. Language
  5. Pure science
  6. Technology
  7. Arts and recreation
  8. Literature
  9. History and geography
  10. Miscellaneous

Within each main class, there are further subclasses and categories that are used to organize the materials in more detail. For example, within the main class “Pure science,” there are subclasses for specific scientific disciplines such as mathematics, physics, and biology.

In general, the main class in a library classification system is used to group together materials that share similar content or subject matter, and it provides a framework for organizing and accessing the materials within the library.

When was DDC developed and who devised it?

Leave a Comment / LIS Studies, Questions & Answer / / / , ,

The Dewey Decimal Classification (DDC) system was developed by Melvil Dewey in the late 19th century. Dewey was an American librarian and library innovator, and he is best known for his contributions to library science, including the development of the DDC system.

According to the Online Computer Library Center (OCLC), the DDC system was first published in 1876. It was initially developed as a way to organize and classify the books in the Amherst College Library, where Dewey was working at the time. The DDC system was later revised and expanded, and it has become one of the most widely used library classification systems in the world.

Dewey is considered to be one of the pioneers of modern library science, and his contributions to the field have had a lasting impact on the way that libraries are organized and managed. In addition to the DDC system, he is also known for his work on library management and administration, as well as his advocacy for universal access to knowledge.

Explain expansive classification?

Leave a Comment / LIS Studies, Questions & Answer / / / ,

Expansive classification is a method of organizing and categorizing information in which a broad main class is divided into a large number of subclasses or categories. This approach is characterized by a high level of detail and specificity, and it is often used to create comprehensive and comprehensive classification systems that cover a wide range of subjects or topics.

One of the main advantages of expansive classification is that it allows for a high level of detail and granularity, which can be useful for organizing and accessing specific pieces of information. However, it can also be more time-consuming and complex to create and maintain an expansive classification system, and it may be more difficult for users to navigate and understand.

In general, expansive classification is a useful approach for creating detailed and comprehensive classification systems, but it may not always be the most efficient or effective method for organizing and accessing information.

What is meant by hospitality in notation/classification?

Leave a Comment / LIS Studies, Questions & Answer / / / ,

In the context of notation or classification, hospitality typically refers to the classification or grouping of businesses or organizations that are involved in the provision of accommodation, food, and other services to travelers and guests. This might include hotels, motels, bed and breakfasts, restaurants, and other similar businesses.

In a classification system, businesses involved in the hospitality industry might be grouped together under a main class or category such as “Hospitality” or “Accommodation and Food Services.” Within this main class, there might be further subclasses or categories that are used to distinguish between different types of businesses or services, such as “Hotels,” “Restaurants,” and “Event Venues.”

In general, the concept of hospitality is an important one in the classification of businesses and organizations, as it helps to identify and distinguish between those that are focused on providing accommodation, food, and other services to travelers and guests.

Leave a Comment / LIS Studies, Questions & Answer / / / , ,

A cutter number is a unique identifier that is used to classify and organize books and other materials in a library. It is named after Charles Ammi Cutter, an American librarian who is credited with developing the concept of the cutter number.

Cutter numbers are typically used in conjunction with the Library of Congress Classification system, which is a system of organizing library materials based on their subject matter. The cutter number is a series of letters and numbers that is assigned to a book or other material based on its subject and the specific classification assigned to that subject. The cutter number is used to locate the material on the library shelves and to distinguish it from other materials with similar subject matter or classification.

Cutter numbers are an important tool for organizing and accessing library materials, and they are used in libraries around the world to help patrons find and borrow the materials they need.

Define literary warrant in classification?درجہ بندی میں ادبی وارنٹ کی تعریف کریں؟

Leave a Comment / LIS Studies, Questions & Answer / / / , ,

In library classification, the term “literary warrant” refers to the justification or authority for assigning a particular call number to a book or other material. Literary warrant is based on the content of the material and the rules and guidelines of the classification system being used.

For example, in the Dewey Decimal Classification system, the call number for a book is based on the subject matter of the book and the specific decimal numbers assigned to that subject. The literary warrant for the call number is the authority or justification for placing the book in that particular subject category and assigning it the corresponding decimal numbers.

The literary warrant for a call number is an important consideration in library classification, as it helps to ensure that the materials are organized in a logical and consistent way, making it easier for patrons to locate and access the materials they need.

Differentiate between natural classification and artificial classification?قدرتی درجہ بندی اور مصنوعی درجہ بندی میں فرق کریں؟

Leave a Comment / LIS Studies, Questions & Answer / / / , ,

Natural classification and artificial classification are two different approaches to organizing and categorizing items or concepts.

Natural classification is a method of classification that is based on the inherent characteristics or traits of the items being classified. It is often used in fields such as biology, where items are classified based on their physical and genetic characteristics. Natural classification systems are typically hierarchical, with broad main classes at the top and more specific subclasses or categories below them.

Artificial classification, on the other hand, is a method of classification that is based on criteria that are chosen by the person or group creating the classification system. These criteria may be based on the intended use or purpose of the items being classified, or they may be based on other arbitrary factors. Artificial classification systems can be useful for organizing items in a way that makes them easy to find or use, but they may not always accurately reflect the true relationships or characteristics of the items being classified.

In general, natural classification systems are considered to be more objective and scientifically rigorous, while artificial classification systems may be more subjective and open to interpretation.
