Definition

The Dewey Decimal call number assigned by the Library of Congress (LC), Library and Archives Canada (NLC), or other national agencies. Use field 082 or field 092 for Dewey numbers assigned by agencies other than LC, NLC, etc.

Use field 082 if you are transcribing Dewey numbers from LC copy or Canadian Cataloging-in-Publication and to identify the edition of the Dewey Decimal Classification (DDC) from which the class number was derived.

If you assign a Dewey Decimal Classification number according to the DDC schedules or to LC practice, use field 092 or field 082 with 2nd indicator 4. If the classification portion of your number does not conform to the DDC schedules, use field 099.

Guidelines

Transcribing Dewey numbers from LC copy

Use the following guidelines for entering Dewey number from LC copy.

Prime marks. Since 1967 LC has divided Dewey class numbers into as many as three segments. LC uses prime marks ( ' ) to separate the segments. The prime marks indicate logical places to shorten a long class number if a library does not want the complete number. If you are transcribing a Dewey class number from LC copy, enter a slash (/) instead of a prime mark.

Dewey number on LC copy Enter
370.19'342 370.19/342

Juvenile works. For works intended for a juvenile audience, a lowercase j is added as a prefix. The j prefix is not added to DDC numbers in records for juvenile textbooks.

Dewey number on LC copy Enter
j574 j574

Juvenile works with [E] or [Fic]. For some juvenile works, LC copy has [E] or [Fic] instead of a Dewey class number. Use field 082 for these designations, include the brackets.

Dewey number on LC copy Enter
[E] [E]
[Fic] [Fic]

Dewey numbers followed by 92 or 920. Use a second subfield a for the 92 or 920.

Dewey number on LC copy Enter
658.404 92 658.404 a 92

Uppercase B in post-1971 numbers. Since January 1971, LC has used an uppercase B to identify works as primarily biographical. If LC copy includes a Dewey number followed by B enclosed in parentheses or brackets, use a second subfield a for the B. Do not enter the parentheses or brackets.

Dewey number on LC copy Enter
942.082 [B] 942.082 a B

LC assigned Dewey numbers according to both the 14th and the 15th editions of the Dewey schedules. From January 1952–November 1958 LC added an asterisk before numbers based on the 15th edition. If you are transcribing such a number, move the asterisk to the end of the number and add 2 15.

If LC copy has two Dewey numbers and one is preceded by an asterisk, use the first subfield a for the number without the asterisk. Use a second subfield a for the other number and move the asterisk to the end of the number.

Dewey number on LC copy Enter
*657.6 657.6* 2 15
*735.29 735.42 735.42 a 735.29*

Series numbers. To indicate a series number, LC uses a lowercase s following a Dewey number. If you are transcribing such a number, enter the number, one space, and the lowercase s.

081s 081 s

Parentheses indicating Dewey numbers assigned to a series. At one time, LC used parentheses to indicate a Dewey number assigned to the series. If you are transcribing such a number, do not enter the parentheses. Enter the number, one space, and a lowercase s.

Dewey number on LC copy Enter
(015.73) 015.73 s

Two Dewey numbers: one in parentheses, one not. If the cataloging is for a serial publication, do not enter the number outside the parentheses. Enter the other number, according to current practice for designating numbers assigned to series: Do not enter the parentheses. Enter the number, one space, and a lowercase s.

Dewey number on LC copy Enter
(015.73) 015.791 015.73 s

If the cataloging is for a nonserial publication, do not enter the number enclosed in parentheses. Enter only the other number.

Dewey number on LC copy Enter
(015.73) 015.791 015.791

Dewey numbers with minus signs. If LC preceded the Dewey number with a minus sign (-), do not enter that number. Some LC copy includes both a "minus" Dewey number and a Dewey number enclosed in parentheses. Do not enter the "minus" number. Enter the other number according to current practice for designating numbers assigned to series. Do not enter the parentheses. Enter the number, a blank space, and a lowercase s.

Dewey number on LC copy Enter
-222.14 [Do not enter such numbers]
-222.14 (927.5) 927.5 s

Dewey numbers in brackets. A Dewey number in brackets is an alternative classification number. If LC copy has one Dewey number enclosed in brackets, enter the number with brackets. If LC copy has two Dewey numbers, and one is bracketed, use the first subfield a for the unbracketed number. Use a second subfield a for the bracketed number.

Dewey number on LC copy Enter
[320.9777] [320.9777]
