Call numbers--Class scheme entry guidelines

Symphony class scheme and call number entry guidelines

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
LC SERIAL LCPER
LC not SERIAL LC
Dewey SERIAL DEWEYPER
Dewey not SERIAL DEWEY
SuDocs any SUDOC
auto-generated any AUTO
excluding |z, call no. is:
numbers only any ASIS
letters only any ASIS
numbers and letters any ALPHANUM

 

Exceptions: LAW uses ALPHANUM for INTERNET RESOURCE call numbers (with |z followed by an abbreviated resource name) and ASIS for Vrooman Collection titles.

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: Call numbers--Subfield z on multipart records.

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.

660 .H424AM
550 .B423
025.4 .I59U ED.2 F

3. SuDocs: Enter call number with one space between letters and numbers unless there is intervening punctuation. This is the same format as the 086 field.
