Excerpt from Decimal Classification and Relativ Index for Libraries, Clippings, Notes, Etc
The field of knowledge is divided into nine main classes and these are numbered by the digits, 1 to 9. Cyclopedias, periodicals, etc, so general in character as to belong to no one of these classes are marked nought, and form a tenth class. Each class is similarly separated into 9 divisions, general works belonging to no division having nought in place of the division number. Divisions are similarly divided into 9 sections and the process is repeated as often as necessary. Thus 512 means Class 5 (natural Science), Division 1 (mathematics), Section 2 (algebra), and every Algebra is numbered 512.
The books on the shelves and the cards in the subject catalog are arranged in simple numerical order, all class numbers being decimals. Since each subject has a definite number, it follows that all books on any subject must stand together. These tables show the order in which subjects follow one another. Thus 512 Algebra precedes 513 Geometry and follows 511 Arithmetic.
