## Index using Dewey Decimal System |

Here are the top-level areas of mathematics and related fields classified according to the Dewey Decimal system, used in many libraries worldwide. For further information about the DDC, visit the Dewey home page or visit the Cyber-Dewey page for applying the DDC to Internet resources. If you need to find resources by DDC number, try this search tool at the Library of Congress.

At this level of generality, the DDC serves only as a coarse guide to the subject areas of mathematics. The system used more commonly among mathematicians is the Mathematics Subject Classification (MSC) scheme, which is the basis for the organization of materials at this site; the list of subfields according to that system is rather longer.

If any DDC aficionado wishes to send in the one hundred or so headings 51x.x it may be possible to convert them to appropriate MSC headings; based only on very limited information it seems appropriate to suggest these links:

510 --- Mathematics

- 510
- 510.1 Philosophy and theory

- 511 General principles of mathematics
- 512 Algebra & number theory
- 512.7 Number Theory
- 512.9 Foundations of algebra

- 513 Arithmetic
- 513.2 Specific arithmetic operations
- 513.5 Numeration systems

- 514 Topology
- 515 Analysis
- 516 Geometry
- 516.2 Euclidean geometry
- 516.3 Analytic geometries
- 516.9 Non-Euclidean geometries

- 517 [unassigned]
- 518 [unassigned]
- 519 Probabilities & applied mathematics
- 519.2 Probabilities
- 519.3 Game theory
- 519.4 Applied numerical analysis
- 519.5 Statistical mathematics
- 519.7 Programming

The Dewey Decimal scheme treats the following as separate from Mathematics but there are some areas of substantial overlap with portions of the MSC:

- 520 Astronomy & allied sciences
- 530 Physics
- 530:
- 530.1 Theories and mathematical physics
- 530.4 States of matter

- 531 Classical mechanics; Solid mechanics
- 532 Fluid mechanics; Liquid mechanics
- 533 Gas mechanics
- 534 Sound & related vibrations
- 535 Light & related radiations
- 536 Heat
- 537 Electricity & electronics
- 538 Magnetism
- 539 Modern physics

- 530:
- 540 Chemistry & allied sciences
- 550 Earth sciences
- 570 Life sciences
- 600 Technology (Applied sciences)
