2. A MARC is a MAchine Readable Cataloguing.
It means that a computer can read and interpret
the data of a cataloguing record.
It is a standard used for the exchange of
bibliographic information among computerised
library systems.
3. The purpose of MARC is to provide a standard
format for the global exchange of bibliographic
information available in Machine Readable
Format in the libraries Worldwide.
Library of Congress, Washington DC was the first
to produced Marc records in October 1966.
4. MARC21 is a new name of the harmonized
CANMARC and USMARC formats. The National
Library of Canada and Library of Congress work
together to formulate a common harmonized format
and reconcile the format differences.
MARC21 is bibliographic standard for 21st century.
All MARC Formats are not the same and majority
have ceased.
5. A FIELD : Each bibliography record is divided
logically into fields. There is a field for author,
a field for title, and so on. These fields are
subdivided into one or more “subfields”. They
are represented by 3-digit tags.
6. A TAG: Each field is associated with 3-digit
number called a “tag”. A tag identifies a field..
The kind of data.. That follows. The tag is
always the first 3-digit. Here the number 100
is the tag.
100 1# $a Amenla AO
7. INDICATORS: Two character position follows
each tag ( with the exception of field 001 through
009).
One or both of these character position may be
used for indicators. When an indicator position is
not used, the indicator is referred to as
“undefined” and the position is left blank.
It is the convention to represent a blank, or
undefined, indicator position by the character
“#”.

The first 24 positions are the leader. In this example the leader fills approximately 1/3 of the first
line and ends with "4500." Immediately following the leader, the directory begins. Tags are
highlighted in green for better understanding. Each individual tag directory is 12 characters long.
The first tag is 001. Following each tag, the next four positions show the length of the field. The
data in the 001 field (control number) in this record is 20 characters long. The next 5 positions tell
the starting point for this field within the data string that follows the directory. The 001 field begins
at the 00000 position (the first position is position 0). The next tag is 003, which is 4 characters long
and begins at the 20th position (the length of the previous position -- 20 -- added to its starting spot
-- 00000 -- equals 20). The next tag is 005. It is 17 characters long and begins at the 24th spot (4 +
20 = 24)

19. The MARC Record structure consists of three
main component : the leader, the directory and the
variable fields.
LEADER: The leader contains the data elements
which provides basic information about the item
and information for the processing of record. The
leader is fixed in length and is 24 characters
beginning from 00 to 23.
20. 00-04 Logical record length ( calculated by the computer)
05 Record status
06 Type of record
07 Bibliographic level
08 type of control
09 character coding scheme
10 Indicator count (always “2”)
11 Subfield code count (always “2”)
12-16 Base address of data ( calculated by the computer)
21. 17 Encoding level
18 Descriptive cataloguing form
19 Linked record requirement
20 length of the length of field portion (always4)
21 Length of the starting character position portion
(always 5)
22 Length of the implementation defined portion
(always 0)
23 Undefined (always “0”)
22. A directory contains information about the tag ,
starting location of each variable field within a
record. Each entry is 12 character positions in
length. The directory is constructed by the
computer program from the bibliographic record,
based on the information contained in the record.
23. As the name suggests, the fields belonging to the variable
fields can be of variable field length.
The variable field can be broadly device into the following
categories i.e.
0XX - Control information, numbers
1XX – Main entry
2XX – Title , area of responsibility, edition, imprint etc.
3XX- Physical description, etc.
4XX – Series statement
5XX – Notes
6XX – Subject added entries
24. 7XX – Added entries other than subject or series
8XX- Series added entries
9XX- Local fields
XX is a digit code between 0 to 9 and represent a variety of
related pieces of information about a particular block.
E.G 1XX is meant for defining the main entry and the
following fields are available.
100 – Main Entry under personal Name
110 - Main Entry under corporate Name
25. 100 Main entry – Personal Name (NR)
Indicator 1 : Type of personal name main entry
◦ 0 -Forename
◦ 1- Surname
◦ 3- family name
Indicator 2: Undefined
◦ $a -personal name
◦ $b - numeration
◦ $c -titles and other word associated
◦ with name ®
26. ◦ $q-fuller form of name
◦ $d-dates associated with a name
(generally year of birth)
E,g 1001 # $a Gregory, Ruth w.
$q (RuthWilliame)
$d 1910
