How do call numbers sort for the different Classification policies?
The following sort rules are used with Classification policies in SirsiDynix Symphony.
| • | ASIS – ASIS means “as is.” It sorts the call number exactly as it is typed. LC or Dewey call numbers do not sort properly with ASIS, but it is appropriate for other kinds of call numbers or accession numbers. |
AV equipment serial numbers like S/N 23456-981 would sort exactly as typed into the call number field.
| • | AT Dewey – Used with the ATDEWEY Classification policy, AT Dewey is for Dewey call numbers sorted by author and title. A 3-letter title cutter or both a 3-letter author and title cutter may be added to the existing call number. A cutter is not added if it already exists in the call number. Any numerals in the call number are expanded to six digits (zero-filled). |
A call number of FIC produces a shelving key of FIC DUN TWO for Dominick Dunne’s book The Two Mrs. Grenvilles. A call number of F STE produces a shelving key of F STE DAD for Danielle Steel’s book Daddy.
| • | AT Dewey with Location – Used with the ATDEWEYLOC Classification policy, AT Dewey with Location is for Dewey call numbers sorted by author and title and preceded by a location. The location is read as typed; the fiction indicator is expanded to three letters, and 3-letter author and title cutters are provided if needed. Any numerals in the call number are expanded to six digits (zero-filled). |
A call number of JUV F CLE produces a shelving key of JUV FIC CLE JAN for the Beverly Cleary’s book Janet’s Thingamajigs in the juvenile JUV collection. The location letters are left as is. The next letters are the fiction marker and are expanded to three characters. The 3-letter cutter for the title is added. The same item with the call number J FIC CLE JAN produces the shelving key J FIC CLE JAN. The expansion and the cutters are not necessary.
The call numbers LP F MIT HAW V.1 and LP F MIT HAW V.2 represent the Large Print edition of James Michener’s Hawaii. The shelving keys are created as: LP FIC MIT HAW V.0000001 and LP FIC MIT HAW V.0000002. The numerals in the volume statement expand to six digits.
| • | CHAR_DEWEY – Maps a single character to a two-digit numerical prefix that is added to the front of a DEWEY call number. This prefix is the primary sort key for the call number. After the prefix, the call number is sorted exactly as a Dewey call number. |
| • | Dewey – Used with the DEWEY Classification policy, Dewey sorts Dewey Decimal nonfiction call numbers. This rule assumes that the first numeral encountered is the classification code, and expands the numeral to three characters. Any preceding letters are location marks to be ignored. Letters after the classification numeral group are to be left as is. Numerals after the classification group expand to six digits. |
A call number of 133.69 BIL produces a shelving key that looks the same: 133.69 BIL. A call number of B 92 LIN produces a shelving key of B 092 LIN. “B” is assumed to be a location marker and is left as is. The first numeral in the call number expands to three digits. A call number of REF 811.42 RUK 1991 produces a shelving key of REF 811.42 RUK 001991. The date “1991” becomes “001991” when expanded to six digits.
| • | Dewey_Sanborn – This sort rule is used for call numbers that have cutters created from the Cutter-Sanborn tables. In order to use this sort rule, a SirsiDynix Symphony administrator must either modify an existing Classification policy or create a new one using the new sort rule. The Cutter Sanborn table cutters are structured in the form: J J1234xyz. |
| • | Expand Numeric – This sort rule expands every numeral in the call number to six digits. |
A call number of QA76.25 .D3 1971 produces a shelving key of QA 000076.000025 .D000003 001971; 92 LIN produces a shelving key of 000092 LIN; and XX(22914.1) produces a shelving key of XX (022914.000001)
| • | LC – This sort rule makes the shelving key appropriate for sorting Library of Congress call numbers. The first numeral after the class letters expands to six digits. Extra spaces are inserted between other parts of the call number to ensure proper sorting. No other numeral groups expand to six digits unless identified as a part/volume number. |
A call number of QA76.25 .D3 1971 produces a shelving key of QA 000076.25 .D3 1971.
| • | LC with Location – This Sort Rule makes the shelving key appropriate for sorting Library of Congress call numbers whose class number is preceded by a location code. |
A call number of REF QA76.25 .D3 1971 produces a shelving key of REF QA 000076.25 .D3 1971.
| • | SuDocs – This Sort Rule makes the shelving key appropriate for sorting SuDoc call numbers assigned to U.S. Government documents. Years are filed before letters, and letters before numbers. (For U.S. Government documents before the year 2000, the first number was dropped from years, so those years have 3 digits.) Call numbers are sorted similar to the following. |
A 1.35:993
A 1.35:R 42
A 1.35:R42/995
A 1.35:R 42/2
A 1.35:321
| • | UDC – This Sort Rule makes the shelving key appropriate for sorting Universal Decimal Classification numbers. |
A call number of 622.341.1=30 produces the shelving key Z622341100J30;
622.341.1(0.035.22) produces the shelving key Z622341100L0.035.22;
622.341.1(=1.366) produces the shelving key Z622341100M1.366;
and 622.341.1”18” produces the shelving key Z622341100N18.
It is recommended that locations not be included as part of the actual call number as indicated in the “with location” options described. The Home Location field of the copy should be used instead.
How do Universal Decimal Classification (UDC) call numbers sort?
In the Universal Decimal Classification system, disciplines of knowledge are divided into 10 classes numbered 0-9. These 10 classes are divided into narrower classes which are hierarchical. Further subdivisions are represented as decimal fractions.
For example:
6 Applied sciences. Medicine. Technology
62 Engineering. Technology in general.
621.3 Electrical Engineering
621.38 Electronics
621.382 semiconductors
Mathematical symbols (such as + and =) and punctuation (such as : and /) are used to link subjects, explain relations between subjects, and define form, language, nationality, etc.
The basic numbers are filed like decimal numbers.
For example:
621.5
621.5.001
621.51
The symbols are filed in the following order.
| • | Plus sign + |
| • | Forward slash / |
| • | Colon : |
| • | Equals sign = |
| • | Closed parentheses ( ) |
| • | Equals sign within closed parentheses (=) |
| • | Minus sign – |
| • | Period . |
For example, for the basic number 621.5, materials would be filed as follows.
621.5+621.7
621.5/6
621.5
621.5:547
621.5(93)
621.5-74
621.5.001
...eventually 621.51 and on
