What kind of notation does DDC use?

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

numbers to each class, category, and subcategory within the classification system. The decimal notation consists of a series of digits, each of which represents a specific level of detail or specificity within the classification system.

For example, in the DDC system, the main classes are represented by a single digit (e.g., 1 for “Philosophy and psychology,” 2 for “Religion,” etc.), and subclasses and categories are represented by additional digits to the right of the main class digit. For example, the subclass “Mathematics” within the main class “Pure science” (class 5) is represented by the number “510,” while the category “Trigonometry” within that subclass is represented by the number “517.”

In addition to the decimal notation, the DDC system also uses a system of captions and notation schedules to provide more detailed information about the meaning and content of each class, category, and subcategory. The captions provide a brief description of the class or category, while the notation schedules provide more detailed information about the specific topics and themes that are covered within each class, category, and subcategory.

Overall, the decimal notation and the system of captions and notation schedules are used together 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 around the world.

Explain close classification?قریبی درجہ بندی کی وضاحت کریں؟

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

Close classification is a type of classification system in which items are organized into a large number of specific or detailed categories. This approach is often used when the items being classified have many distinct characteristics or attributes that can be used to distinguish between different categories.

In a close classification system, the categories are typically defined by a set of specific or detailed characteristics, and the items are assigned to the categories based on which characteristics they possess. For example, in a close classification of animals, the categories might include mammals, birds, reptiles, and fish, and the animals might be further classified into subcategories based on specific characteristics such as their size, shape, or habitat.

One of the main advantages of close classification is that it allows for a high level of detail and precision. Because the categories are specific and detailed, it is possible to assign items to very specific categories, making it easier to locate and access specific items.

However, one of the main limitations of close classification is that it can be complex and may require a lot of effort to create and maintain. It can also be difficult to change or modify a close classification system once it is established.

Overall, close classification is a useful tool for organizing and categorizing items in a logical and structured way, but it may not be the most suitable approach in situations where the items being classified are very diverse or where the classification system needs to be highly flexible.
