Multifunctional digital devices are classed with their predominant function, e.g., personal digital assistants (PDAs), which often include mobile phone and portable media player capabilities in addition to their baseline computing capabilities, with handheld computing devices 004.167. However, a work that focuses on a specific function other than the predominant function is classed with the specific function, e.g., audio recording using a personal computer 006.5

Groups of people: Tips for classifying complex works

• Provisions for groups of people:

• T1—08 Groups of people

• Table 5. Ethnic and National Groups

• Provisions for groups of people in schedules, e.g., 305 & 362

• Provisions for topics in schedules, e.g., migration

• Citation order / preference order

Citation order

The order in which two or more characteristics (facets) of a class are to be combined in number building. When number building is not permitted or possible, instructions on preference order with respect to the choice of facets are provided. (from Glossary)

Preference order

The order indicating which one of two or more numbers is to be chosen when different characteristics of a subject cannot be shown in full by number building. A note (sometimes containing a table of preference) indicates which characteristic is to be selected for works covering more than one characteristic. When a notation can be synthesized to show two or more characteristics, it is a matter of citation order. (from Glossary)

302-307 Table of preference replaces instruction to class with last (1)

Factors affecting social behavior 304

Social processes 303

Social interaction 302

Culture and institutions 306

Groups of people 305

Communities 307

Class comprehensive works in 301. Class effect of one factor on another with the factor affected, e.g., effect of climate on social change 303.4
