• Part 1. Elements of typical call numbers

• Part 2. Class numbers

• Part 3. Book numbers and other methods of subarrangement

### Part 1. Elements of typical call numbers

• Call number = class number + book number (or other method of alphabetic subarrangement)

• Example:

• 641.5972

• .B3433

### 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.

### 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

### 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

### Other method of alphabetic subarrangement

• Instead of formal book numbers, many libraries prefer simple methods of alphabetic subarrangement

• Example: Bay for Bayless, Rick

### Part 2. Class numbers

• Broad classification and logical abridgment

• Building with tables (numbered auxiliary tables)

• Building with other add notes

• 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.

### Logical abridgment

• The abridged number is the same as the full number, but shorter

• The number is abridged at a logical place

### 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.

### 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

### 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

### 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 won’t be able to cover all six auxiliary tables; we will cover the following tables:

### 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

### 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 T1—09 from Table 1) with any number from the schedules, e.g., wages (331.29) in Japan (T2—52 in this table): 331.2952 ; railroad transportation (385) in Brazil (T2—81 in this table): 385.0981

### 641.593-641.599 Cooking characteristic of specific continents, countries, localities

Add to base number 641.59 notation T2—3-T2—9 from Table 2 , e.g., Southern cooking (United States) 641.5975

T2—75     Southeastern United States (South Atlantic states)

Class here southern states

641.59+[T2—]75=641.5975

### 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

### 641.59+[T2—]45=641.5945 (etc.)

• 641.5945 Italian cooking

• 641.59455 Cooking of Tuscany

• 641.59458Cooking of Sicily

• 641.595 Asian cooking

• 641.5951 Chinese cooking

• 641.5952 Japanese cooking

### 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.

### 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.

### 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.

### 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 (T1—076 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

### T1—09 Historical, geographic, persons treatment

• T1—092 Persons

Biography, autobiography, description and critical appraisal of work, diaries . . .

Class here treatment of individuals

• T1—093-T1—099 Treatment by specific continents, countries, localities; extraterrestrial worlds

### T1—09 Historical, geographic, persons treatment

• T1—093-T1—099 Treatment by specific continents, countries, localities; extraterrestrial worlds

Add to base number T1—09 notation T2—3-T2—9 from Table 2, e.g., the subject in North America T1—097, in Brazil T1—0981

### 630  Agriculture and related technologies

### 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 ( T5—9726 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 T2—174 from Table 2

### 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 T2—1 or T2—3-T2—9 from Table 2 for area in which a group is or was located, e.g., Germans in Brazil T5—31081 , but Germans in Germany T5—31 ; Jews in Germany or Jews from Germany T5—924043

### 305.805-305.89 Specific ethnic and national groups

Add to base number 305.8 notation T5—05-T5—9 from Table 5, e.g., comprehensive works on Jews 305.8924, Chinese 305.8951, Chinese Australians 305.8951094, Inuit 305.89712

305.8+[T5—]951+0+[T2—]94= 305.8951094

### 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 subarrangement—but they are optional

### Arrange alphabetically

• Rare instruction in DDC

• Always optional

• 006.74 Markup languages

Arrange alphabetically by name of language, e.g., XML

• 006.74

• .X6

### Arrange chronologically

• Rare instruction in DDC

• Optional

• 796.98 Winter Olympic games

Arrange specific games chronologically

• 796.98

• 2006

### Individual biographies

• Arrange alphabetically by name of biographee

• Example: biography of forester Emile Grandjean

• 634.9092

• .G764

### 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 author’s name.

• As with all forms of subarrangement, double Cuttering is not part of DDC proper

### Example of double Cuttering

• Biography of forester Emile Grandjean

• Grandjean : man of the forests

By Gordon S. Bowen

• 634.9092

• .G764B6754
