    LISBDNETWORKBy Updated:4 Comments2 Mins Read
    Notation plays an important role in library classification as it is used to organize and classify books and other materials in a systematic and logical way. Some of the key functions of notation in library classification include:Functions of Notation in Library Classification
    1. Stands in place of terms used in the scheme of classification so that whenever the term is to be represented, it may be represented by a class mark only.
    For example:

    • The terms Mathematics, Chemistry, & Physics are referred to by the notation (In DDC) 510, 530, and 540, respectively.

    2. Shows the sequence of schedules and subordination of subjects. That means it not only stands in place of terms but also acts as a guide to locate their position of them in the schedules.
    For example:

    Let’s take some terms used in DDC.  The terms Mathematics, Astronomy, and Physics do not convey  any one of their places in the schedules, but anyone can easily understand when we say:

      • 510 – Mathematics.
      • 520 – Astronomy.
      • 530 – physics.

    3. Search to connect alphabetical order or index with the systematic order of schedules. That means consulting the number attached to the index entry; one can easily find out the place of the subject in the classification schedules.

    4. search to connect the catalogue with the shelves. The symbol written on the spine of the book is also written on the cards of the individual’s books; hence by consulting the catalogue one can find out the exact location of a book or books on the shelves.

    5. Maintenance systematic order on the shelves. The arrangement of books on the shelves should follow the systematic order shown in the classification scheme.

    • i.e., main class past, division, sub-division, etc.
    6. Notation assists in the efficient guidance of a library.
    7. Its mnemonic qualities help a librarian remember the sequence of division within a class.
    8. It helps to insert a new topic in the classification without changing the classification number.
    9. It helps to divide a broader subject into various smaller divisions and then to arrange them in a convenient form.
