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...

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...

Usefulness of Notation Notation is a series of symbols which stands for the name of a class or any division or sub-division of a class, and forms a convenient means of reference to the arrangement of a classification. Summarizing its usefulness, a notation: Stands instead of the terms of a classification. It is a constant...

A classification is said to have mnemonic value when its notation has the power of “aiding the memory”, i.e. when some of its symbols have more or less the same significance wherever they appear in the schedules or more correctly, when certain aspects are always represented by the same symbols throughout the schedules. Mnemonic devices...

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. The symbol are sub-divided...

2. Shows the sequence of schedules and subordination of of subjects. That means it not only stands in place of terms but also acts as a guide to locate the 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 there places in the schedules, but anyone can easily understand when we say:
3. Search to connect alphabetical order or index with the systematic order of schedules. That means consulting the number attach to the index entry, one can easily find out the place of subject in the classification schedules.
4. search to connect the catalogue with the shelves. The symbol written in the spine of the book are also written on the cards of the individuals 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 on the classification scheme.

Harrods Librarian Glossary (Tenth ed.) “The symbols which stand for the divisions in a scheme of classification.”
Harrods Librarian Glossary “A Notation is the ordered, series or symbol that stand for the ordered, series or terms in the classification schedule.”
W. Howard Phileps “A book notation is a series of symbols in which stand for the name of a class or any division or subdivision of a class and forms of a convenient means of reference to the arrangement of a classification.”
H.E Bliss “Notation as a system of marks and symbols in some order, denoting terms or member of a series or system of things.”
A book notation is a series of symbols which stands for the name of a class or any division or subdivision of a class, and forms a convenient means of reference to the arrangement of a classification.
The notation is an important addition to a classification scheduled; it has in no way determined its logic, its scope, or its sequence of development. It furnishes a convenient reference to the arrangement of a classification; the symbol is not assigned until after the schedule has been worked out. it has no more bearing on the preparation of the logic of a classification outline than the chapter numbers of a book have in fixing the t5hemes of those chapters.
In most book classifications the notation is a symbol that stands for either the subject of the book, or the style of writing. Since the notation is a sign translation of the classification, it usually ensures, when it is added to the backs of books, a book arrangement which represents the order of the schedules.
A notation then, is essential for the practical application of book classification; without notation it would be impossible to apply classification to books. As classification is the “foundation of librarianship”‘ it can be said that”notation is the basis of practical book classification”.

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.
The symbol are sub-divided from -01-09. Basically this notation are added to the base numbers by omitting the dash (-) to make a complite class number wherever necessary.
whenever the notation or symbols of this table are added to any main class of the schedules it express the same meaning always.
For Example:
(530 is main class & .0202 always implies as standard sub-division. 530= Physics, 300= Social Science)
Here -0202 always imply the same things i.e. manual, which is mnemonic.
Table-2 : Areas:
The Notation of table 2 represent the geographical area of the world. The intend of the notation of this table to add with main class and indicates the areas.
For Example:
this .5499 always indicate Bangladesh, so we may call it mnemonic.
Table-3 : Sub-division of individual literature:
Literary works are written and published in different form i.e. poetry, fiction, drama, etc. The notation or symbols of the table are used to express the affordable form of literature. Moreover after adding with any main class of the schedules it always expresses the same meaning.
For Example:
here -3 imply fiction in each contrast, which is mnemonic.
Table-4 : Sub-division of Individual Languages:
Basically problems of language are expresses wit the help of the notation of this table. It may be Spelling, Grammar, Pronunciation etc. This type of notation only use to indicate language pass.
For Example:
So -5 is always indicating grammar which is mnemonic.
Table-5 : Racial, Ethnic and National Groups:
The symbol or notation are use to represent race, ethnic and nations. This symbol are added main class and express the racial and national groups of any work.
For Example:
here -9144 stands for Bangaili which is mnemonic.
Table-6 : Language:
To express the translate language, the medium of language, and the influential languages over another language, the symbols of this table or notation is use.
For Example:
In this context 9144 always represents Bangla Language which is mnemonic.
here – 0901 always imply academician in both cases and we may call it mnemonic
