The class scheme in Symphony determines how the shelving key is generated, which in turn determines how call numbers sort. The shelving key field should not be directly edited. Consistency of sorting will depend to some extent on spacing conventions used, and on the appropriate use of subfield z to separate the base call number from volume or part numbering. In addition, a browse call number search will return more consistent results if the search is qualified by class scheme.
A. Class Scheme
Apply the following guidelines to assign the appropriate class scheme for a given call number. LC, Dewey and SuDocs numbers have special sort rules, and are not treated as straightforward alphanumerics. The "PER" extension indicates that multiple call numbers will display in descending order, i.e., the highest numbered or latest volume displays first.
|Call no. type||Format||Class scheme|
|excluding |z, call no. is:|
|numbers and letters||any||ALPHANUM|
Exception: LAW will use alphanum.
Note: for a given title, ascending or descending display can be specified regardless of the class scheme. With the full record displayed in the OPAC, click on the "QUALIFY" button, and on the "VIEW OPTIONS" screen, set "Order of call numbers" to ascending or descending.
B. Call Number Entry
Apply the following spacing and punctuation conventions when entering a call number of a given type. In Symphony, all letters are upper case. Enter one space before a size designator (T, F, FF). There is no space before or after a subfield z. For more information on subfield z, see separate guidelines: Use of subfield z in the call number field in Symphony.
1. LC: enter call number with one space and one period before the first cutter, and one space before the second cutter, embedded date, or scale. Enter one space before the date of publication in a monographic call number. Call numbers imported via Smartport from the 050 field should load with correct formatting.

2. Dewey: enter call number with one space before the first cutter. Enter one space before a date of publication or edition statement for a monographic call number.
