OCLC Online Computer Library Center DDC number building for shelf arrangement Julianne Beall Assistant Editor, DDC Library of Congress July 4, 2006 Vienna

OCLC Online Computer Library Center Broad outline Part 1. Elements of typical call numbers Part 2. Class numbers Part 3. Book numbers and other methods of subarrangement

OCLC Online Computer Library Center Part 1. Elements of typical call numbers Call number = class number + book number (or other method of alphabetic subarrangement) Example: 641.5972.B3433

OCLC Online Computer Library Center Call number A set of letters, numerals or other symbols (in combination or alone) used by a library to identify a specific copy of a work. A call number consists of the class number and book number (or Cutter number). It may also contain other data such as date, volume number, copy number and location symbol.

OCLC Online Computer Library Center Class number Notation that designates the class to which a given item belongs. Example: 641.5972 Cooking characteristic of Mexico Used for Rick Bayless's Mexican kitchen : capturing the vibrant flavors of a world- class cuisine

OCLC Online Computer Library Center Book number The part of a call number that distinguishes a specific item from other items within the same class number, also called a Cutter number. A book number is composed of letters from the author's name and numbers. Example:.B3433 for Bayless, Rick From OCLC Cutter Four-Figure Table

OCLC Online Computer Library Center Other method of alphabetic subarrangement Instead of formal book numbers, many libraries prefer simple methods of alphabetic subarrangement Example: Bay for Bayless, Rick

OCLC Online Computer Library Center Part 2. Class numbers Broad classification and logical abridgment Building with tables (numbered auxiliary tables) Building with add tables Building with other add notes

OCLC Online Computer Library Center Broad classification The classification of works in broad categories by logical abridgment, even when more specific numbers are available, e.g., the use of 641.5 Cooking instead of 641.5972 Mexican cooking for a cookbook of Mexican recipes.

OCLC Online Computer Library Center Logical abridgment The abridged number is the same as the full number, but shorter The number is abridged at a logical place

OCLC Online Computer Library Center Abridged edition A shortened version of the Dewey Decimal Classification (DDC) system that is a logical truncation of the notational and structural hierarchy of the corresponding full edition on which it is based. The abridged edition is intended for general collections of 20,000 titles or less.

OCLC Online Computer Library Center Segmentation marks (/ or ) Records from Library of Congress and Library and Archives Canada include segmentation marks in Dewey class numbers These marks show end of abridged number The slash (/) appears in MARC records The prime mark () appears in Cataloging in Publication printed in books

OCLC Online Computer Library Center Example of segmentation 641.5/6314 The abridged number (641.5) means cooking The full number (641.56314) means cooking for people with diabetes Never include segmentation marks in call numbers

OCLC Online Computer Library Center Building with tables (numbered auxiliary tables) Numbers from auxiliary tables are never used alone for shelf arrangement They may, however, be used alone in a database for resource discovery Today we wont be able to cover all six auxiliary tables; we will cover the following tables:

OCLC Online Computer Library Center Tables to be covered today Table 2. Geographic Areas, Historical Periods, Persons Table 1. Standard Subdivisions Table 3A. Subdivisions for Works by or about Individual Authors Table 3B. Subdivisions for Works by or about More than One Author Table 5. Ethnic and National Groups

OCLC Online Computer Library Center Table 2. Geographic Areas, Historical Periods, Persons The following numbers are never used alone, but may be used as required (either directly when so noted or through the interposition of notation T109 from Table 1) with any number from the schedules, e.g., wages (331.29) in Japan (T252 in this table): 331.2952 ; railroad transportation (385) in Brazil (T281 in this table): 385.0981

OCLC Online Computer Library Center 641.593-641.599 Cooking characteristic of specific continents, countries, localities Add to base number 641.59 notation T23- T29 from Table 2, e.g., Southern cooking (United States) 641.5975 T275 Southeastern United States (South Atlantic states) Class here southern states 641.59+[T2]75=641.5975

OCLC Online Computer Library Center 641.59+[T2]436=641.59436 (etc.) 641.59436 Austrian cooking 641.5943613Cooking of Vienna 641.5944 French cooking 641.59442 Cooking of Normandy 641.59449 Cooking of Provence

OCLC Online Computer Library Center Facet Any of the various categories into which a given class may be divided, e.g., division of the class "people" into the categories of ethnicity, age, education and language spoken. Each category contains terms based on a single characteristic of division, e.g., children, adolescents and adults are characteristics of division of the "ages" category.

OCLC Online Computer Library Center Facet indicator A digit used to introduce notation representing a characteristic of the subject. For example, "0" is often used as a facet indicator to introduce standard subdivision concepts.

OCLC Online Computer Library Center Rule for logical abridgment Never abridge a number so as to leave a 0 or other facet indicator at the end, in the part following the decimal point Dewey numbers may end with 0 before the decimal point Examples: 630 is O.K. 630.90 is not O.K. 630.9 is O.K.

OCLC Online Computer Library Center Table 1. Standard Subdivisions The following notation is never used alone, but may be used as required with any regular schedule number, e.g., workbooks (T1076 in this table) in arithmetic (513): 513.076. When adding to a number from the schedules, always insert a decimal point between the third and fourth digits of the complete number

OCLC Online Computer Library Center T109 Historical, geographic, persons treatment T1092 Persons Biography, autobiography, description and critical appraisal of work, diaries... Class here treatment of individuals T1093-T1099 Treatment by specific continents, countries, localities; extraterrestrial worlds

OCLC Online Computer Library Center Table 5. Ethnic and National Groups The following numbers are never used alone, but may be used as required (either directly when so noted or through the interposition of notation T1 089 from Table 1) with any number from the schedules, e.g., civil and political rights ( 323.11 ) of Navajo Indians ( T59726 in this table): 323.119726 ; ceramic arts ( 738 ) of Jews ( T5 924 in this table): 738.089924. They may also be used when so noted with numbers from other tables, e.g., notation T2174 from Table 2

OCLC Online Computer Library Center Table 5. Ethnic and National Groups (2) Except where instructed otherwise, and unless it is redundant, add 0 to the number from this table and to the result add notation T21 or T23-T29 from Table 2 for area in which a group is or was located, e.g., Germans in Brazil T5 31081, but Germans in Germany T531 ; Jews in Germany or Jews from Germany T5924043

OCLC Online Computer Library Center Part 3. Book numbers and other methods of subarrangement All methods of subarrangement are optional and not part of DDC proper Many different methods of subarrangement are used in Dewey libraries In a very few places in the DDC there are instructions for subarrangementbut they are optional

OCLC Online Computer Library Center Arrange alphabetically Rare instruction in DDC Always optional 006.74 Markup languages Arrange alphabetically by name of language, e.g., XML 006.74.X6

OCLC Online Computer Library Center Arrange chronologically Rare instruction in DDC Optional 796.98 Winter Olympic games Arrange specific games chronologically 796.98 2006

OCLC Online Computer Library Center Individual biographies Arrange alphabetically by name of biographee Example: biography of forester Emile Grandjean 634.9092.G764

OCLC Online Computer Library Center Double Cuttering If you use Cutter numbers to arrange alphabetically by topic (e.g., name of biographee), you may then add a second Cutter number for the authors name. As with all forms of subarrangement, double Cuttering is not part of DDC proper

OCLC Online Computer Library Center Example of double Cuttering Biography of forester Emile Grandjean Grandjean : man of the forests By Gordon S. Bowen 634.9092.G764B6754
