Specifying Spine Breaker Categories

If you want to use spine labels, you need to set up spine breaker categories. Spine breaker categories determine the way call numbers print on spine labels. When a call number will not fit on a single line of a label, the spine breaker category determines where the numbers will be divided and wrapped to the next line.

You can implement spine breakers in two different ways:

Automatic call number division. In the Edit Call Number Type view, you can specify the spine breaker method you want to use for the selected call number type. Then, when you print spine labels, Horizon automatically divides and wraps call numbers that are longer than the width of the label.
Spine breaker override. Staff can enter special characters directly into a record’s call number field to override the automatic call number division and force the division of the call number on a printed spine label. These are the valid characters: question mark ( ? ), back slash ( \ ), and pipe ( |).

Horizon does not allow the forward slash ( / ) for spine breaker override. There is a conflict between the use of this character as a spine breaker and the sudoc format.

The automatic spine breaker categories are predefined according to call number type. This task explains how to change the spine breaker category assigned to a given call number type. The predefined methods (called procedures) are stored in the mqmr73.dll file.

If you need help in changing the procedures or DLLs assigned to a spine breaker category, contact your system implementor or Customer Support.
