3. BIBLIOGRAPHICAL WORK
COLLECTIVE
2
1. INDIVIDUAL BIOGRAPHY
Individual biography includes single person biography. About their life,
lessons, how he affect the people life. The subject which is related to him.
Rule: - we take subject first and then 092 from table for individual
biography.
e.g.:-A life of J.R.D.Tata = 338.0092

4. The book is individual biography of J.R.D.Tata and the subject is business so
number of business from volume 2 is 338. So in that we add .092 from table
1 because table is applicable is for everything.
2. COLLECTIVE BIOGRAPHY
Collective biography includes collection of biography more than one person.
Sometime it may be from same subject, area, gender, time or may be from
different time, gender, area, subject or combinations of these.
A) Work limited subject in which all group of people / all personalities
contributed.
Rule: - if work is limited on only one subject but two or more people include
in this then first subject number and for collective biography 0922 from
table 1 .
E.g.:- Great teachers=371.100922
The book is about teacher. Education is subject.
Because subject is same so that’s why main entry under subject class
number that is education in that 371.1 for teachers. Standard subdivision
is 1008-1009 that’s why 0092 we used for collective biography from table
1.
work limited to time not limited to area or subject
Rule: - if work is limited to time not limited to area and subject then entry
under main class biography that is 920 and add era number.
E.g.:-Great personalities of the 19th
century= 920.009034
This book is including all persons from different country and different.
Entry under biography. 00901-00905 is for historical period .so base number
920.0090 un that add the number following 090 in notation 0901-0905 from
table 1 i.e. for 19th
century 09034 . But following number 090 means exclude
the 090 that’s why we take only 34.

5. B) work limited to specific area (geography)
Rule: - if work limited to specific area then entry under biography class and if
subject is given then make entry under subject. Then add area class number from
table 2 as per the instruction.
E.g. .i) Musician of India=780.92254
The Book is about Indian musician.
780 for music then from table 1 (.0922) for collective biography. Now see the
standard subdivision of subject that is .1-.9 so zero will be cancel.Astric mark
was there that’s why we saw the summary .in summary they mention add
subject base number from notation 3-9 from table 2,from table 2 we got the
India number i.e.54 .
ii) 6 great English men=920.042
This is biography about six English men. English men means they belong to
country England.
Here subject is not mentioned that’s why entry under 920.0. Now as per
instruction notation 3-9from table 2 for country number. 42 England code.
D) Work limited to gender
Rule: - if work is limited to gender then for women the 920.72 and for men it is
920.71
E.g. i) Great women of modern India = 920.72
ii) Hand in hand =920.71
Hand in hand is about the ten black men who change America.
These both entries under biography class number, in that in subdivision of
biography this number is mentioned for women and men.
Work not limited to area, subject, time, gender.

6. Rule: - if work is not limited to anything then make entry under general
collection of biography that is 920.02.
E.g. Hall of fame=920.02

prescriptive from table 4.
Descriptive means grammar, dictionaries, etymology, historical and
geographical variation, phonology, phonetics. And prescriptive means
which allow us to practice or teach us, and for learning.
