MARC 21 Classification Format

Full Level Record - DDC Schedule,
Class 003

Network Development and MARC Standards Office
Library of Congress

The following example illustrates MARC classification records for classification numbers between 003.3-003.71 (computer modeling and simulation; theory of communication and control; kinds of systems; large-scale systems) from volume 2 of the Dewey Decimal Classification, 21th edition. Entries from the DDC manual are also encoded in the records when they refer to the classification number in field 153. Examples are shown in numerical tag order; however it may be necessary in some cases to add a subfield $8 (Field link and sequence number) to 6XX and 76X fields to ensure the correct ordering of fields.

Scheme:
  003.3 Computer modeling and simulation
      Standard subdivisions are added for either or both topics in heading

Class here data processing and computer science applied to systems, computer implementation of mathematical models of systems, interdisciplinary works on computer modeling and simulation

Add to base number 003.3 the numbers following 00 in 004-006, e.g., computer simulation languages 003.3513

For computer modeling and simulation applied to a specific subject, see the subject plus notation --0113 from Table 1, e.g., computer modeling in economics 330.0113

    Kinds of systems
Many kinds of systems are defined in terms of the equations used to model
them, e.g., distributed-parameter systems are defined as systems governed by partial differential equations. Other equations may be used to model the behavior of the same real-world system. Class a work about a specific kind of system according to the way the work describes the system, e.g., a work that discusses applying the mathematics of stochastic (random) processes to systems 003.76.
