In
library classification, the mnemonics means the power of adding the
memory that means some of its notational symbols have more or less
the same significance through out the classification schedule. Colon
classification scheme is best example of mnemonics. Dr. S R Ranganathan
has used four types of mnemonics in colon classification.
(a)
verbal mnemonics
(b)
schedule mnemonics
(c)
seminal mnemonics
(d)
systematic mnemonics
Verbal
mnemonics
Verbal
mnemonics is the letter for notational symbol for a class and
subclass. So the verbal mnemonics consist in representing a class
by first or more letter generally maximum three letters in the name.
First letter should be English capital and after may be small but
only alphabet are used. For example
(According
to Colon Classification 6.0)
Basmati Rice J381 B
Begmi Rice J381 Be
Scheduled
mnemonics
Scheduled
mnemonics can be defined a systemic list of divisions, tables or
parts of schedules. According to Dr. Ranganathan , “a scheme of
classification should include a preliminary set of schedules of
isolate likely to occur in any array of some order or other of all or
several classes or it should refer any recurrent sets of isolates to
the one schedule of them given in connection with an appropriate
basic class”.
Scheduled mnemonics consists following devices
(1)
Common isolate Device
(2)
Geographical Device
(3)
Chronological Device
(4)
Subject Device
(5)
Facet Device
(6)
Phase Device
Examples:

Flora of India I:12.44
Fauna of India K:12.44
Anatomy of neck L17:2
Anatomy of eye L184:2
Seminal
mnemonics
Seminal
mnemonics means specified digit should be seminally equivalent
to entire schedule that means the same concepts is represented by the
same term and also same number in entire schedule, if any conflict
occurs, then we simply say that particular classification schedule
ignore this concept. In colon classification entire schedule divide
into seminal mnemonics such as
Number
Meaning
1 Fundamentals, preliminary, persons
2 Structure, parts, forms, constitute
3 Function, syntax, method analysis
4 Fault, disease, pathology
5 Liquid, blood, environment
6 Money, finance, evolution, movement
7 Personality, composition, growth, produce
8 Management, organization
Systematic
mnemonics
Systematic mnemonics represent the sequence of isolate in array
that means the schedule arrange according to some rules such as
later-in-time, arrangement of isolates according any principles.
Colon classification gives well defined systematic mnemonics such as
in Medicine Main Class(L) the class number arranged according to
human body structure from upper parts to lower. Space schedule
arranged according to most nearest to far distance. Similarly we can
also examine the main class Psychology(S), the personality facet [p]
are arranged according to growth such as new born, toddler, boy,
middle age and old age.
