Take a look at the following call numbers. Are they in the right order? What are the differences between each call number?
PN 197.52 |
PN 197.6 |
PN 197.649 |
PN 197.68 |
They are in the correct order. The only difference is in the subject number lines. Now look at the next example. Are the call numbers in the right order? What is the difference between each of the call numbers?
Z 1003.3 |
ZA 1003.3 |
ZA 1003.3 |
These are also in the correct order. The difference between the first call number and the other two is that the first one is subject class Z while the other two are subclass ZA. The difference between the second and the third call numbers is the copy number.
While these two sets represent highly unlikely coincidences, the point is that one must pay careful attention to the small details.
The following example is ordered incorrectly. How should they be ordered?
DA 247.3 .A637 F22 2006 |
DB 766 .H266 B76
|
DB 766 .H2556 B76 2003
|
DB 766 .H2556 B132 2009
|
DG 247.1 .H502 C821 2000
|
DC 325.5 .H567 C81 2000
|
The correct order is as follows:
DA 247.3 .A637 F22 2006 |
DB 766 .H2556 B132 2009 |
DB 766 .H2556 B76 2003 |
DB 766 .H266 B76
|
DC 325.5 .H567 C81 2000
|
DG 247.1 .H502 C821 2000 |
