Call Number Format (Revised) 10/08/11 - Western Cataloguing Specifications

Call numbers are unique identifiers assigned to library materials to indicate their physical location within the Library collections. A UWO call number consists of some or all of the following elements:

1. Location/Collection Designator

2. Class Number - consists of some or all of the following:

  • One, two, or three capital letters
  • Whole numbers 1 to 9999
  • Possible decimal extensions
  • Topical/Geographic (T/G) Cutter number

UWO uses Library of Congress or National Library of Medicine Classification Schedules to formulate class numbers.

3. Book (Cutter) Number

4. Chronology (Date)

5. Caption and Enumeration

CAPTION is a word or phrase, usually in abbreviated form, that identifies the type of parts into which a multipart or serial unit has been divided, e.g. volume, tome, Band, Heft, part, number. Caption is usually the same as is used on the publication. For list of caption abbreviations see Abbreviations and Terms Used on Spine Labels.

ENUMERATION is the number used for numeric designation of the part. Roman or other numerals in the publication must be translated into arabic.

6. Copy Number - The designation indicating the specific copy of a bibliographic unit.

Call numbers assigned to serials consist only of the basic elements (Location/Collection Designator, Class Number, Book (Cutter) Number, Copy Number). Field 966 does not include holdings descriptors, i.e. subfield codes $d-$i.

Labelling of serials with complete call number for each individual piece is the responsibility of the Inventory Control Staff. Standards and procedures for labelling serials are outlined in the Inventory Control Manual. A list of abbreviations for use as serial captions are also included in the Manual. FIHDES is not applicable.


Serial within a series classified as a collection:

The following are examples of practices which have been discontinued as a result of summary holdings complications. New serials within a series classified as a collection must be questioned:

DBWSTK
F
1421
.T95
no.15

Composite series numbering (no.15 etc.) appears no.15 only in the cataloguing record. Each physical piece etc. has its own series number on the spine label, e.g.

F
1421
.T95
no.18 (v.2 of serial)
F
1421
.T95
no.28 (v.3 of serial)

 

ENGSTK

Caption used to keep all the volumes of a serial together. It is part of the call number on individual pieces in the serial.

v.1 v.3
copy 2 1992
copy 2


No spacing required between multipart copy 2 item call number and copy number. Copy 1 is suppressed in the printing of spine labels.

The current practice is to always place Copy number as the last component of the call number on the spine label.

Previously the practice regarding the placement of the copy number for multipart items varied. Copy number may not have been the last component of the call number on the label. For adders, the cataloguers must observe the current practice and leave the discrepancies for Inventory Control staff to resolve.

Prior to 1992, the practice for serials was to include copy number as part of 099 and 966$s. This practice has been discontinued. Retrospective clean up is taking place.
