PREFACE.

The plan of the following Classification and Index was developed early

in 1873. It was the result of several months' study of library economy

as found in some hundreds of books and pamphlets, and in over fifty

personal visits to various American libraries. In this study, the author

became convinced that the usefulness of these libraries might be greatly

increased without additional expenditure. Three years practical use of

the system here explained, leads him to believe that it will accomplish

this result; for with its aid, the catalogues, shelf lists, indexes, and

cross-references essential to this increased usefulness, can be made

more economically than by any other method which he has been able to

find. The system was devised for cataloguing and indexing purposes,

but it was found on trial to be equally valuable for numbering and

arranging books and pamphlets on the shelves.

The library is first divided into nine special libraries which are called

Classes. These Classes are Philosophy, Theology, &c., and are

numbered with the nine digits. Thus Class 9 is the Library of History;

Class 7, the Library of Fine Art; Class 2, the Library of Theology.

These special libraries or Classes are then considered independently,

and each one is separated again into nine special Divisions of the main

subject. These Divisions are numbered from 1 to 9 as were the Classes.

Thus 59 is the 9th Division (Zoology) of the 5th Class (Natural

Science). A final division is then made by separating each of these

Divisions into nine Sections which are numbered in the same way, with

the nine digits. Thus 513 is the 3d Section (Geometry) of the 1st

Division (Mathematics) of the 5th Class (Natural Science). This

number, giving Class, Division, and Section, is called the Classification

or Class Number, and is applied to every book or pamphlet belonging

to the library. All the Geometries are thus numbered 513, all the

Mineralogies 549, and so throughout the library, all the books on any

given subject bear the number of that subject in the scheme. Where a 0

occurs in a class number, it has its normal zero power. Thus, a book

numbered 510, is Class 5, Division 1, but no Section. This signifies that

the book treats of the Division 51 (Mathematics) in general, and is not

limited to any one Section, as is the Geometry, marked 513. If marked

500, it would indicate a treatise on Science in general, limited to no

Division. A zero occurring in the first place would in the same way

show that the book is limited to no Class. The classification is mainly

made by subjects or content regardless of _form_; but it is found

practically useful to make an additional distinction in these general

treatises, according to the form of treatment adopted. Thus, in Science

we have a large number of books treating of Science in general, and so

having a 0 for the Division number. These books are then divided into

Sections, as are those of the other Classes according to the form they

have taken on. We have the Philosophy and History of Science,

Scientific Compends, Dictionaries, Essays, Periodicals, Societies,

Education, and Travels,--all having the common subject, =NATURAL

SCIENCE=, but treating it in these varied forms. These form

distinctions are introduced here because the number of general works is

large, and the numerals allow of this division, without extra labor for

the numbers from 501 to 509 would otherwise be unused. They apply

only to the general treatises, which, without them, would have a class

number ending with two zeros. A Dictionary
