What is meant by mnemonics?

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

A mnemonic is a memory aid that is used to help people remember specific information. Mnemonics are commonly used to remember lists, sequences, or facts that are difficult to commit to memory, and they typically use associations, acronyms, or other techniques to link the information to be remembered with something that is easier to remember.

There are many different types of mnemonics, and they can be used in a variety of settings, including education, business, and personal development. Some common examples of mnemonics include:

  • Acronyms: Words or phrases that are formed from the first letters of the items to be remembered. For example, “Roy G. Biv” is a mnemonic used to remember the colors of the rainbow (red, orange, yellow, green, blue, indigo, violet).
  • Acrostics: Phrases or sentences in which the first letter of each word represents the item to be remembered. For example, “Every Good Boy Deserves Fudge” is a mnemonic used to remember the lines of the treble clef in music notation (E, G, B, D, F).
  • Rhymes: Words or phrases that are easy to remember because they rhyme with the items to be remembered. For example, “30 days hath September, April, June, and November” is a mnemonic used to remember the number of days in each month.

Overall, mnemonics are useful tools that can help people remember specific information more easily and effectively.

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

There are a few potential drawbacks to using the Dewey Decimal Classification (DDC) system:

  1. Complexity: The DDC system is a detailed and comprehensive classification system, and it can be complex to use, especially for users who are unfamiliar with the system. It may take some time and effort to learn and understand the decimal notation, the captions, and the notation schedules, and this can be a challenge for users who are new to the system.
  2. Limited subject coverage: The DDC system is designed to cover a wide range of subjects and topics, but it may not include all of the materials that a library needs to classify. In some cases, libraries may need to use additional classification systems or create their own custom classifications to cover specific subjects or topics that are not covered by the DDC system.
  3. Inflexibility: The DDC system is designed to be flexible and adaptable, but it may be less flexible than some other classification systems. For example, the system may not allow for easy reclassification of materials as new knowledge or subject matter becomes available, and it may not be as easy to customize or tailor the system to meet the specific needs and goals of individual libraries.
  4. Limited ability to reflect changes in knowledge and subject matter: The DDC system is regularly updated and revised to reflect changes in knowledge and subject matter, but it may not be able to keep pace with rapid changes in certain fields or disciplines. This can be a drawback for libraries that need to classify materials in rapidly evolving or emerging fields, as the DDC system may not always be

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.

Who invented book classification?کتاب کی درجہ بندی کس نے ایجاد کی؟

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

The concept of book classification has a long history, and it is not possible to attribute the invention of book classification to a single individual. However, there have been many people who have contributed to the development and evolution of book classification systems throughout the history of library science.

One of the earliest known book classification systems was developed by the ancient Greeks, who organized their libraries according to the subjects of the works contained within them. In the Middle Ages, monks and scholars developed more sophisticated systems of book classification, including the system of classification used in the Vatican Library, which is considered one of the oldest surviving library catalogues in the world.

In the modern era, several individuals are credited with significant contributions to the development of book classification systems. One of the most well-known figures in the history of book classification is Melvil Dewey, an American librarian who developed the Dewey Decimal Classification system in the late 19th century. Another important figure in the history of book classification is Charles Ammi Cutter, an American librarian who developed the concept of the cutter number, which is used to classify and organize books in the Library of Congress Classification system.
