Abbreviation and Enumeration
- CWAN titles should be assigned call numbers with enumeration
matching the piece numbers on the series title page of the item. The
series title page usually precedes the title page for the individual
- Enumeration for volumes that are relabeled for any reason should
be changed to meet the current abbreviation standards. Write the new
enumeration in the back of the book, enter it into the 866 ‡a and into
the Item record enumeration box.
- We will use the
current list of abbreviations for any piece level indications when an
item comes to Resource Management for maintenance and the corrective
action requires that the piece go to processing for relabel. The
bibliographic and holding record should be edited to reflect the
updated call number. The holding
record printout inserted in the book for the processor should reflect
updated call number.
Bibliographic records for AV items should contain an 090 (subject
classification) and an 099 (actual call number to be placed on the
AV items are assigned accession numbers. Items with multiple copies in
multiple locations will be assigned the same accession number when
Capitalization in the 090 or 050: Piece level abbreviations and
“lettered” parts in the call number field are entered in all lower case
letters. Letters following the date in the call number are to be lower
case. Title cutters for children’s literature and similar cases are
entered with the initial letter capitalized and others lower case.
- Class numbers aren’t yet in the schedules for the most recently
published authors and correct placement of
these items in the collection is a priority. We will relabel items and
correct the records for items that have been assigned an incorrect
for the author when initially cataloged.
- DLC and other libraries have been assigning some call numbers
as if the titles were part of a CWAN set. We should accept the 2nd
class number offered, move the information to an 090 field and add the
appropriate cutter. Only CWAN sets should have enumeration in the call
number field. If these records (DLC or non-DLC) lack the appropriate
to correspond with the 2nd class number, then it is
to add appropriate subject headings to the bibliographic record. Staff
use Classweb to determine which subject headings to add or consult the
staff assistant for assistance.
The date in the fixed field, at the end of the
number and in the 260 field must be identical for most material. One
exception to this rule is that conference dates are accepted for the
call number instead of the publication date.
When working with older items from the stacks that
are in need of record maintenance for any reason, we must make sure
edit the matching bibliographic record. Through some project work, I’ve
noticed an interesting occurrence that has made matching records in
to books in the collection more difficult. Publication dates have been
to the bibliographic record call number field for many older volumes.
change was not reflected on the book in many cases. If the publication
in the book and the date added to the call number match, then you can
assume that the record is for the book in hand.
If we are not withdrawing the book and there is no
other reason to relabel it, please remove the date from the call number
in the bibliographic and holding records. The label on the spine and
MFHD should contain the same call number information.
The final element in the call
is almost always the year of
publication. There are some cases in which it is necessary to add a
work letter following the date to distinguish the work you are
cataloging from other similar

also, with a large print edition published in the same year as the
The author classification for "selected works" also
the work letter "b" for 2nd editions in the same year. The author
for "collected works" has separate cutters for type of work and does
use the work letters.
A: LC uses the work letter
"a" for :
- Photocopies or "true"
facsmiles. They use the same call number as the original work, with the
date of the original work, plus the work letter "a", so that the
or facsimile will shelve directly next to the original work.
- "Dump numbers". This
term refers most often to a cutter used in which no way represents the
main entry. An example is the biography table, where A3 represents an
autobiography classed in an individual biography number. If two
autobiographies by the same person were published in the same year, LC
uses the "a' to distinguish them (e.g., .K56 A3 1997 ; .K56 .A3 1997a)
- N class: exhibition
catalogs or collections of an artist. When two of either occur in the
year, LC's practice is to consult the .xA4 part of the table for
artists on the first cutter; the second work published in the same year
take work letter "a" tacked onto the date (e.g. .V36.A4 1996; .V36.A4
- Works entered under
a corporate body (110). The first work published in a particular year
gets that year added to the call number; subsequent works published in
the same year get work letters starting with "a" (usually serial).
- Works entered under
a conference or congress (111, or sometimes 110). If a date is present
in the heading, LC uses that date in the call number; subsequent works
the same heading get the same date with work letter starting with "a"
NOTE: LC doesn't "reserve" the work
letter "a" in these situations. In these cases, they don't keep
editions together, nor does LC use translation numbers or selection
Work letters and usage
- “p”; To distinguish
between a score and set of parts for the same work with
identical cutters, add "p" to the date of publication in the
for the set of parts (e.g., M452.B455 1965p).
- "x"; not generally used
by LC, this "trailing x" is most often used by other institutions to
distinguish their call number from an LC call number, and is most often
found tacked onto the cutter rather than the date; early in the NCCP
project, libraries like Harvard used trailing x's.
- “z”; when a date in
the 260 field is incomplete, such as 19--, add the date as 1900z. If
another publication arrives of the same work with the same incomplete
that will become 1900za. For an uncertain decade of publication in the
such as 195-, use the form 1950z.
- "z"; is also used for
commentaries on a specific conference, where the name of the conference
is usually the first subject heading assigned. The call number consists
of a class number, a cutter number for the conference, the date of the
conference (from the conference heading), and work letters starting
with "z" letters such as "za, "zb", and so on).
- Serials entered under a
corporate body or conference. Here, the first work received would take
work letter "a" tacked onto the cutter; subsequent works would take
letters "b", "c", and so on.
- Multiple work letters.
In certain exceptional cases, LC will use all 26 letters tacked onto
the date. The best example of this is class HA201 for the census of the
United States. This class is subarranged by the date of the census, but
with no cutters.
They use "aa", "ab", and so on as needed.

The application will differ for each class (subject). The goal is to
the titles in numeric order while allowing room for expansion for
numeric titles in that specific class area. Ask the staff assistant or
catalog librarian for assistance in assigning these cutters as needed.)
Call numbers with no
cutter, but including a year should be entered into the 852 field of
the Holdings record screen in Voyager as follows:
There is one space
between the classification number and the date.
We will no longer use REF DESK as a call number for items to be shelved
there. Voyager is capable of reflecting this location in the 852 ‡b
field. All items cataloged for the reference desk should be set for
REFDESK location in the MFHD and have an 049 field prefix of REF.
Punctuation (LC call numbers)
The first cutter of an LC format call number is the only element
of a call number which requires a deciaml preceding it. The first
by a decimal regardless of the field and subfield placement. The second
cutter is not punctuated. Call numbers with no cutter require no
punctuation for the basic call number.
Call numbers extended by more than one element beyond the basic call
number require commas separating the elements.
Please note the punctuation in the examples below:
PN37 ‡b .B29
PN22.P32 ‡b C48 1821
JK1405 ‡b 1999
Extended by one element beyond the basic call number (date):
KF8961 ‡b .N49 2007
Extended by two elements beyond the basic call number (comma required):
T61 ‡b .A561 56th, 2007
All books arriving for cataloging with call
numbers of PZ1, PZ3, and PZ4 should be reclassified to their subject
etc.). Other PZ’s can remain.
Bibliographies arriving for cataloging with call numbers beginning with
Z1000 and above will be reclassified to fall into their subject area.
Do not reclassify Z1000 titles whose primary subject field (650)
contains "book" or "books."
