Classification involves grouping similar entities together and separating dissimilar entities in a systematic order. Library classification arranges documents by classifying their subjects. It is a translation of the subjects into a preferred artificial language of ordinal numbers for arrangement on shelves or description.
There are various principles, schemes, structures, and devices used in library classification. Some key aspects include facets, isolates, decimals, and mnemonics to aid memory. Works are done at the idea, verbal, and notational planes which can be carried out independently. Various canons also provide guidelines for characteristics, succession, arrays, language use, and notations to build an effective classification system.

Library of Congress and Sears List of Subject Headings.pptxSubhajit Panda
Subject headings are the creative initiative of a librarian from his love to organise things. Technically, subject headings are the standardized words assigned to a concept. Using subject headings helps to decrease the “junk,” or irrelevant results. And it is based on the theme of the topic, not the words that appeared in the text. According to Charles A. Cutter, the most important subject cataloguing principle was a consideration of the best interest of the catalogue user. Cutter stated: “The convenience of the public is always to be set before the ease of the cataloguer”. This presentation focuses on the two most popular subject heading lists: Sears List of Subject Headings (SLSH) and Library of Congress Subject Headings (LCSH). Starting from an overview and background study, this project further nurtures the work architecture, functionalities, usage, advantages and disadvantages of each of the selected subject heading lists.
A comparative analysis of library classification systemsAli Hassan Maken
We use classification each & every moment of the life by intentionally or unintentionally. Classification has always been the backbone of all Library operations and without it, library is definitely going to suffer in its recourse and to find a particular piece of information from unorganized heap of knowledge is almost impossible. The library classification is core instrument for organizing and retrieval of the documents stored in a library. At present era they are the navigation tools for locating and retrieving documents in more precisely and relevantly. The electronic versions of the DDC and UDC and other classification schemes make it possible to realize the potential of library classification to improve subject retrieval.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

31. 3 PLANES OF WORK-3 PLANES OF WORK- 1952 SRR1952 SRR
IDEA- Class(used in the idea plane)
Verbal- Subject
Notational- Class number
32. Working towards the dvt of a dynamic
theory of library clsn led to the fact that
the design and application of a scheme for
lib clsn involves work in the
IDEA,VERBAL and NOTATIONAL plane,
which are separable and can be carried
out independently.
33. IDEA PLANEIDEA PLANE
Man > sankrit> mana=to think.
The organ of thinking is called Manas=mind.
Mind- place of origin of ideas.
SRR-idea is the product of thinking.
Ideas = communication through the medium
language.
34. The basic work of lib clsn takes place at
the idea plane.
The efficiency of a scheme will largely
depend upon the quality of theory of lib
clsn used for work in the idea plane .
Ideas must be represented at the verbal
plane in standardized and precise term.
35. VERBAL PLANEVERBAL PLANE
Human being possess the capacity to create
ideas.
Capacity to develop and articulate language as a
medium for communication of the ideas.
The verbal plane involves expression of
concepts in a natural language.
Since ideas are formed faster than words, every
natural languages proves to be inadequate.
36. Work at the verbal plane has to be
carried out for each natural language
separately.
The terms used should be current in use.
Therefore, there need to be develop
technical terminology free from
homonyms and synonyms for each
discipline.
37. Require cooperation between specialists
and linguists.
It would be better if international
nomenclature is established and adopted
for use.
To overcome the problems of natural
languages, some classification schemes
add an annotation after the terms.
38. For this purpose, SRR has suggested that
a classification should follow the canon of
both context and enumeration for the
designing of schedules for clsn.
39. NOTATIONAL PLANENOTATIONAL PLANE
Continuous attempts are being made to
make language precise.
Often words are replace by symbols.
Lib Clsn: deals with artificial language of
ordinal digits, which is called classificatory
language.
These ordinal digits are used as helpful
symbols for the arrangement of
documnts.
40. NL is used by common man but
classificatory language is not widely use.
Classificatory Language is restricted only
to arrangement of subject, isolates and
commodities.
A classificatory is a controlled language,
controlled by the classificationist.
It doesn’t develop homonyms &
synonyms
41. Universe of knowledge is dynamic
CL must be developed to meet the
onslaught of the Uk
The notational system for such a language
must be versatile.
The work at notational plane must be
carried out continuously so that
notational plane would be able to fulfill
the demands of the idea plane.
42. Canons for Idea PlaneCanons for Idea Plane
a. Canons for characteristics
b. Canons for succession of characteristics
c. Canons for array
d. Canons for chain
e. Canons for filiatory sequence.
43. Canons for characteristicsCanons for characteristics
Each characteristics of an associated
scheme of characteristics used in a
scheme of library classification should
satisfy following four canons:
a. Canon of differentiation
b.Canon of relevance
c. Canon of ascertainability
d.Canon of permanence.
44. Canons for succession of characteristicsCanons for succession of characteristics
The succession of characteristics in the
associated scheme of characteristic
should satisfy the following three canons:
a. Canon of concomitance
b.Canon of relevant succession
c. Canon of consistent succession.
45. Canons for Verbal PlaneCanons for Verbal Plane
Natural language is imperfect since there is
vagueness in the meaning and not free from the
incidence of homonyms and synonym.
Therefore, in classificatory language precise
terms with their uniqueness in meaning should
be used.
SRR formulated 4 canons for verbal plane. Both
classificationist and classifier must follow these
canons for work at the verbal plane.
46. Canons for Verbal PlaneCanons for Verbal Plane
a. Canon of context.
b. Canon of enumeration
c. Canon of currency
d. Canon of Reticence
47. Canons for Notational PlaneCanons for Notational Plane
A notational system consists of ordinal
numbers representing classes n a scheme
for classification. The notational system
used for the classification of universe of
subjects should follow the basic canons of
notations.
48. Canons in the notational planeCanons in the notational plane
a. Canons for uniqueness of notation
i. Canon of Synonym
ii. Canon of homonym
b. Positive and its negative canons.
49. Canon of SynonymCanon of Synonym
“the class number of a subject in a system
of class numbers and the isolate number
of an isolate idea in a system of isolate
numbers should be unique”
CC avoids the provision of synonyms class
numbers. However one violation is there
under [S] isolate i.e. ‘2’ Mother country.
Library can use ‘2’ & 44 for India.
50. Canon of HomonymCanon of Homonym
“the subject represented by a class
numbers in a system of class numbers and
the isolate idea represented by an isolate
number in a system of isolate numbers
should be unique”
Each class number should represent one
and only one subject.
DDC violates-954
UDC,CC avoids homonyms
51. Positive and its negative canonsPositive and its negative canons
10 canons which are to be satisfied by
the notational system of any scheme for
classification.
These canons fall into five pair in such a
way that each pair consists of one canon
and of its negation.
52. Positive and its negative canonsPositive and its negative canons
i. Canon of relativity and canon of uniformity
ii. Canon of Hierarchy and canon of non-
hierarchy
iii. Canon of mixed notation and canon of pure
notation
iv. Canon of faceted notation and canon of non-
faceted notation.
v. Canon of co-extensiveness and canon of
under extensiveness.

56. Cow Calf PrincipleCow Calf Principle
If a facet A and another facet B belonging to the
same subject are not to be separated though
they distinct from each other and thus
separable, A and B should be kept together in
the same round, even as a milchy cow and its
unweaned calf are not separately sold out
though they are distinct entities and thus
separable, but are kept together in possession
of the same owner.

60. NOTATIONNOTATION
In library clsn notation is an artificial
language in which the subject of a
document is translated or coded.
Different types of notations are being used
by different schemes for the purpose of
clsn of books.
63. Notation is an artificial language or
ordinal numbers which represent various
classes in a scheme for clsn.
For more helpful arrangement a notation
may consists of more than one type of
symbols.
Hence, notation should act as a
mechanical device for arrangement of
books on shelves.
64. Need/RequisiteNeed/Requisite
To arrange the documents in a helpful
sequence for its quick retrieval notation
is very much needed in library
classification.
Ranganathan has given some reasons
which justify the need of notation in
library clsn which are:
65. i.i. Unhelpfulness of alphabetical sequenceUnhelpfulness of alphabetical sequence
Since alphabetical arrangement of subjects by their
names is not helpful, it must be ruled out. Eg if we
arrange ten main classes of DDC according to
alphabetical arrangement by their names then Pure
Sciences will fall between Philosophy and Religion.
Similarly Religion and Sociology will falls between pure
science and Technology.
Thus it would lead to a unhelpful sequence. Thus it
would lead to a unhelpful sequence. Rather it would be
helpful, if Pure Science and Technology could be kept
together.
66. ii.ii. Effect of change in name of subject.Effect of change in name of subject.
Since the name of subjects are not stable
i.e. they keep on changing from time to
time, alphabetical arrangement of subjects
by their names to mechanize the
arrangement must be ruled out. Eg.
Physics was earlier named as Natural
Philosopy.
67. iii. Effect of synonyms on alphabetical sequence.iii. Effect of synonyms on alphabetical sequence.
Since the use of synonyms i.e. subjects
with more than one name is a common
feature, alphabetical arrangement of
subjects by their names to mechanise the
arrangement must be ruled out. Eg.
Acoustic and Sound are equivalent terms
denoting the same branch of Physics.
68. iv. Effect of homonyms on alphabetical sequence.iv. Effect of homonyms on alphabetical sequence.
Since the use of homonyms i.e. one and the
same term used to denote a variety of ideas in
a natural languge is a common feature,
alphabetical arrangement of subjects by their
names to mechanise the arrangement must be
ruled out.
Eg. Term ‘Number’ represent integer, rational
number, irrational number, transcedental
number, imaginary and complex number and so
on.
69. v. Effect of multiplicity of languages on alphabeticalv. Effect of multiplicity of languages on alphabetical
sequence.sequence.
Since the alphabetical position of a
subject would vary with the language
from which the name is taken alphabetical
arrangement must be ruled out. Eg. In
english ‘Dry Cell’ would go the ‘D’ group
and ‘Tuning Fork to the ‘T’ group. But in
German the former goes to ‘T’ group
and the latter to the ‘S’ group.
70. Thus it becomes clear that alphabetical
arrangement fails to mechanize the
arrangment in a preferred helpful
sequenc, and there is necessity of use of
ordinal numbers in notation.
71. Functions of notationFunctions of notation
Helps in mechanical arrangement of documents.
Serves as a guide to the sequence of terms and fixes
their relative positions.
Rearranging of documents when misplaced.
Allows mechanical reference to be made from any
catalogue entry to the material on the shelves.
Notation with its mnemonic qualities assists the library
staff to remember the sequence of divisions within a
class.
Hospitality in library clsn can be secured by
manipulating notation.
72. functionsfunctions
Helps in the arrangement of entries in
bibliographies, documentation lists
Useful for preparing various guides used
in the library.
73. Types of notationTypes of notation
Types of notatin depends upon the
various digits used in making the notation.
On this basis notation can be of two
types.
1. Pure notation
2. Mixed Noation
74. Pure NotationPure Notation
When the notational system of any
classification scheme uses only one type
of symbols or digits, it is called pure
nation.
Eg Arabic numerals or Roman Capital or
Roman Smalls.
75. Mixed NotationMixed Notation
When the notational system of any
classification scheme uses more than one
type of digits or symbols, it is called as
mixed notation.
Eg. Indo-arabic numerals and Roman
Capitals and Roman Smalls.
78. BrevityBrevity
In a class number, brevity is a desirable quality.
In library, for compactness books are usually
made to stand side by side on their lower edges
with only the spines visible. Therefore, class
number of a book must be written on its spine.
Since the average thickness of book is only one
inch, the digits of class number should not be
longer than an inch the digits of class number
should not be longer than an inch and
preferably shorter.
79. This can be achieved by the use of wide
base such as alphabetical base and
allocation of symbols to the classes
keeping in view their sub-classes.
80. Speed of writingSpeed of writing
A notation should admits of speedy
writing since the class number of each
book is entered in several places such as
on the spine, the date label, the back of
the title page, in secret page, in accession
register etc.
81. SimplicitySimplicity
Notation should be as simple as possible
i.e. it should be easy to write to
pronounce and to remember. Here ‘easy
to write’ indicates that each symbol or
sign used in national system should be
clearly identifiable from one another. An
easy to pronounce indicates that notation
should be easy to read. Easy to
remember is also an important quality
82. ExpressivenessExpressiveness
The notation which expresses the
structure of the scheme is known as
expressive, hierachial or structural.
It helps the users to find his way up in a
systematic order in the structure of the
classification scheme.
Good notation should reflect both
coordination and subordination
relationship
83. Flexibility/HospitalityFlexibility/Hospitality
There has been continuous growth in
various field of universe of knowledge.
Therefore, notation should possess the
quality of hospitality so that it can
accomadate any number of new subjects.
Hospitality means flexibility, expansibility
or adjustability.
In CC,DDC,UDC sufficient hospitality
has been provided in array & chain
84. SynthesisSynthesis
Synthesis means number building by
taking components of the number from
different part of the schedules. Both
faceted and enumerative schemes of
classification synthesis components from
different parts to form compound
numbers. However synthesis is more
pronounced in faceted schemes of
classification.
85. DDCDDC
Mixed notational system
MS, DIVISION, SECTIONS
Coordinate and subordinate relationship
among the classes
Provides lots of hospitality in its array
and chain.
Possess the qualities such as brevity and
expressiveness.
87. The notation of CC is much flexible than
DDC. It provides a lot of hospitality in
array and chain. Besides this it possesses
other qualities of a good notation such as
simplicity, expressiveness and synthesis.

In case of conflicts between canons,
principles and rules: it should be resolved.
92. LAW OF IMPARIALITYLAW OF IMPARIALITY
Between two or more claimants (first
position among 2 facets) preference
should be made only on sufficient
grounds and not arbitrarily.
Eg.
1. Sequence of facets: Wall Picture Principle
2. CC ed 1, “9”-empty digit but law suggested other
species of digits i.e. Roman smalls & caps should be
used as empty digit
93. LAW OF IMPARIALITYLAW OF IMPARIALITY
3. Connecting digit in CC from 1952-1963:
same connecting digit was used for [S] &
[T] i.e. ‘
94. LAW OF SYMMETRYLAW OF SYMMETRY
Of two entities or situations which admits
of being regarded as symmetrical
counterparts of each other, if one of
them is given weight in some context, the
other too should be given a
corresponding weight
95. LAW OF SYMMETRYLAW OF SYMMETRY
a. Species of digits in CC: SRR allocated
greater ordinal value to Roman Caps
than Indo Arabic Numbers.
Later Roman Smalls were used as PCI and
were given lesser ordinal value than
Indo Arabic numerals satisfying the law
of symmetry.
96. LAW OF PARSIMONYLAW OF PARSIMONY
Between to or more possible alternatives
bearing on a particular phenomena, the
one leading to overall economy of
manpower, material, money and time is
to be preferred.
Eg. CC employs various devices-
CD;GD;SD
Legnth of Class Number
97. Law of Local VariationLaw of Local Variation
This law directs towards the formation of
special collection separate from general
collection.
Word “Local” should be interpreted as to
refer to a geographical area of any size
such as American; European interests etc.
98. Law of Local VariationLaw of Local Variation
Eg.
[S] isolate: digit 2 & 3
2: Monther country
3: Favoured country
Favoured Language [-] dash
99. LAW OF OSMOSISLAW OF OSMOSIS
Owing to the canon of context, if a change
in the catalogue code or classification
scheme becomes essential, then from a
particular date following works should be
carried out:
1.Classify and catalogue all newly
accessioned documents according to new
classification scheme and cataloguge code
100. LAW OF OSMOSISLAW OF OSMOSIS
2. Re-classify and re-catalogue the
documents which are much in use.
3. Maintain two catalogues i.e. old and new
catalogue and its sequence on the shelf
4. Reference librarian should direct the
attention of the users to both the
catalouges.
