- 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.
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.
