Classification number used for subject access. It is taken from Dewey Decimal Classification and Relative Index, the Abridged Dewey Decimal Classification and Relative Index, and electronic updates to either edition. Through 1997, updates were issued in DC& Dewey Decimal Classification Additions, Notes and Decisions.
First Indicator - Type of edition
Indicates the edition from which the Dewey Decimal classification is taken.
Class number was taken from the full edition.
| 082 | 04$a388.13$222 | ||||||||
| 083 | 0#$z2$a4947$222 For a book on tunnels in the Swiss Alps. The Dewey number 388.13 is used for interdisciplinary works on tunnels, but the number itself is broader, covering a variety of special road features. Consequently, geographic area notation cannot be added to the primary number in field 082. Field 083 contains the geographic area notation from Table 2 for the Swiss Alps. |

Class number was taken from the abridged edition.
The edition is specified in subfield $2 (Edition number).
Second Indicator - Undefined
Undefined and contains a blank (#).
$a - Classification number
Additional classification number applied to the resource, which could be used for subject access in addition to the primary classification number assigned.
| 082 | 04$a599.0994$222 | ||||||||
| 083 | 0#$a598.0994$222 | ||||||||
| 083 | 0#$z2$a94$222 For a book on Australian birds and mammals. The Dewey number 599 is used for works on mammals and for comprehensive works on birds and mammals. The rest of the primary number in field 082 consists of 09 Geographic treatment from Table 1 and 94 Australia from Table 2. There is no way to tell from this number whether the book contains information about birds or not. The Dewey number 598 in the first 083 field means birds, and the full number means birds in Australia. The second 083 field has the Table 2 area number for Australia; it is intended to help users seeking everything about Australia. |

Display Constant
| [ ... ] | [brackets] |
Square brackets enclosing a DDC number that appear on printed products are not carried in the MARC record. They may be system generated as a display constant associated with the field tag.
Standard or optional designation - If subfield $m is present, only one subfield $a should be coded, unless the value in subfield $m applies to all numbers in repeated occurrences of subfield $a. Otherwise, the field is repeated.
