Section 3A.4 :
Call Number Practices and Format
These are local practices.
“P” PRACTICES:
PZ numbers are not used — If Juvenile — see instructions for Juvenile Collection, if other, change call number to appropriate classification.
PS 8001-8599 Do not use. Reserved for National Library of Canada.
“Z” PRACTICES:
Z 1000 through Z 7999. Most libraries prefer to class with the subjects in other parts of the schedules.
Z 4 through Z 1039 are ok.
ZA 3040+ Information resources are ok.
“L” PRACTICES:
L call numbers for math and science books. Public Service and Education has requested that we catalog books on math and science from Q to L for “elementary” books that have a classification established in L classification schedule. For advanced books, secondary, etc., keep the Q number.
Other
Cutter numbers should only end in 1 or 0 (one or zero) when instructed to in the schedules.
Works with main entries beginning with Roman or Arabic numerals are generally cuttered between .A12-.A19
CALL NUMBER FORMAT
When checking call numbers be sure the call number is formated correctly. Generally, call numbers will follow patterns similar to those below.
A correct call numbers may look like this:
| BX | REF |
| 2380 | HA |
| .C3 | 2345.78 |
| D44 | .U5 |
| 1987 | M35 |
| 2002 |
Example – on an OCLC record ……..….. 090 BX2380 ≠b .C3 1987 v.1
- on a Voyager bib. record ….. 090 ≠a BX2380 ≠b.C3 1987 v.1
In some call numbers you may see unusual formatting because some items – like constitutions of countries, works of music, conferences, etc. – may be arranged by year, work number, opus, etc. You may see legitimate call numbers that may look like:
| KF | KF |
| 4558 | 141 |
| 14th | 1970 |
| 1970 | .A52 |
| .P45 | |
| 2001 |
***Call numbers that should alert you that something is wrong:
| PS | QC | HV | RA234 | 914.7/03/84 |
| 2345 | 346 | 6788 | .P67 | .O63 |
| .445 | .B3C3 | .H45 | 1988 | |
| 1998 | 1989 | .P6 |
When in doubt — ASK!
