You already know that DDC consist of seven tables. For your detail information all of the tables and their mnemonic values are discussed in below: Table-1 : Standard Sub-division: The notations of this tables are huge to express the point of view from and intend of huge of any subject field.

Mnemonic devices usually result from a mechanical manipulation of the notational symbols. The simplest example of mnemonics is that... Read more »

It is obvious from the use made of a notation that the symbols standing for topics in the schedules should: Notation should reflect order: The Notation must indicate order that mean the symbols use to represent the topic should indicate the position of that topic in hierarchy of it main class or division. Notation should be assemble as fetchable: Simplicity of notation depend on the length of notation and on the type... Read more »

Function 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 refereed to by the notation (In DDC) 510, 530and 540 respectively 2. Shows the sequence of schedules and subordination of of subjects.
