Prepared by:

At the September 14, 1990 meeting of the IO Cataloging Congress,
representatives of the various IO cataloging agencies approved a
system-wide standard for the subfielding of both Library of
Congress and Superintendent of Documents (SuDoc) classification
numbers in IO copy holdings statements.
The attached document serves only as a guide to this standard. Not
all unusual or exceptional cases of classification numbers have
been reported.

LC Classification Numbers Standard
for
IO Copy Holdings Statements
|b Class Number
Subfield |b contains the class number (that part of the number
which pertains to the subject of the work as assigned from the LC
classification schedules). A space is never input between the
class letter and number.
|c Book/Item Number
Subfield |c contains that part of the number pertaining to the
individual piece. Dates or words that follow the item number (i.e.
extensions) are placed in an additional subfield |c for each unit.
I. Single Cutter
Standard: |b ML5 |c .E568
|b G108 |c .A289
|b JX1974.7 |c .M5
NOT: |b ML5.E568
|b ML 5 |c .E568
II. Double Cutters
Standard: |b HF5314.V52 |c U54
|b LB234.4.C2 |c M36
NOT: |b HF5314 |c .V52 |c U54
|b LB234.4 |c .C2 |c M36
|b LB 234.4 |c .C2 |c M36
EXCEPTION: If the class number exceeds the present 12
character limit in the subfield |b, divide the number
where the marks of punctuation indicate logical breaks.
|b HF3230.56 |c .Z63 |c R43
I. Extensions
|b G108 |c .A289 |c 1959
|b Z1205.A5 |c C3 |c no. 12

|b Z1223 |c .C75 |c Suppl.
|b JX21 |c .C22 |c Index
|b S1 |c .R43 |c Cum. Index
IV. Punctuation within Extensions
a. Elements within extensions containing two periods
are placed in one subfield |c:
|b Z5502 |c .D45 |c Cum. Ind.
b. Extensions containing both a period and a comma are
placed in one subfield |c:
|b L105 |c .C33 |c v. 3, 5
c. If multiple extensions result in a call number which
is too long for the IO copy holdings statement,
spaces between letters and numbers within the
extensions may be deleted. Likewise, words may be
further abbreviated:
Too long: |b HF3230.56 |c .Z63 |c R43 |c v. 31, |c no. 14-100
Try: |b HF3230.56 |c .Z63 |c R43 |c v.31, |c no.14-100

Hints on Inputting Call Nos.
August 14, 1992
Carolyn Sherayko
HINTS ON CALL NUMBERS IN COPY HOLDINGS STATEMENTS
There are several ways that typos in call numbers will prevent
the number from indexing in the call number index. It is important
for accurate shelflisting in IO that call numbers are input
correctly.
1. Do not put an end-of-field mark (i.e. [ctrl,F4]) at the end
of a call number.
2. Capitalize the class or subclass letters in a Library of
Congress number.
3. Be sure that subfield marks are input correctly.
Use | (shift, backslash keys), not }, ], or \
4. Do not include extraneous characters or punctuation.
Incorrect: Correct:
|b .F2986 |c .H75 |b F2986 |c .H75
|b BQ7602 |c .W118 |b BQ7602 |c .W118
|b PS3515.\M53 |c Z58 |b PS3515.M53 |c Z58
5. Be sure the punctuation is located in the proper subfield.
Incorrect: Correct:
|b DK274. |c H25 |b DK274 |c .H25
6. Do not use brackets in call numbers.
Incorrect:
|b PL788.4.G4 |c A333 |c [v. 2]
Correct:
|b PL788.4.G4 |c A333 |c v. 2
7. Be sure that the classification number is complete.
Incorrect: Correct:
|b 1108 |c .Z84 |c 1974 |b HD1108 |c .Z84 |c 1974
8. Do not use the lower case letter "L" to represent the number
"1"
9. REFORMAT the copy holdings record after inputting a call
number and REVIEW the number.
Hints on Call #s for Unlinked Item Records
September 3, 1992
Carolyn Sherayko
HINTS ON CALL NUMBERS IN UNLINKED ITEM RECORDS
Since the call number is one of the few ways we can find unlinked
item records, it is very important that they are input correctly.
Using the following guidelines will help assure the quality of the
information in IO.
1. Be sure that the "CLASS TYPE:" is set correctly:
L = Library of Congress call number (begins with letters
and numbers)
GR487 .G797
D = Dewey call number (begins with numbers)
363.7392 KOR
S = Superintendent of Documents (used with government
documents)
C 3.2/2:F 35/986
O = Other (can be anything)
No call number 88B-721
FIC CRU E LIP
2. CAPITALIZE the initial letter(s) of all call numbers beginning
with letters. For Library of Congress and Superintendent of
Documents numbers, capitalize all letters.
No call number
HD8066 .S56
3. Do not use the lower case letter "L" to represent the number
"1"
4. Do not include location information as part of the call number
even though it may be printed above the call number. The
following are examples of locations and should not be
included:
O.J. Picture UGBC
O.K. Geolmfiche SLIS
O.C. Manipulative HPER Microfiche
Video Slide
5. Do not put the barcode in the call number field.
6. Input the call number at the beginning of the call number
field. If there are spaces or extra punctuation at the
beginning, the call number will not appear in the call number
index.
