PUBLISHED BY THE UNIVERSITY
HHIS BULLETIN is the ninth of a series of bulletins pub-
lished by the Engineering Experiment Station of j the
University of Illinois. The Engineering Experiment .
Station was established by action of the Board of Trus-
tees December 8, 1903. It is the purpose of the Station to carry
on investigations along various lines of engineering, and to study .
problems of importance to professional engineers and to the man-
ufacturing, railway, mining, constructional and industrial inter-
ests of the state.
The control of the Engineering Experiment Station is vested
in the heads of the several departments of the College of En-
gineering. These constitute the Station Staff, and with the Di-
rector determine the character of the investigations to be under-
taken. The work is carried on under the supervision of the Staff ;
sometimes by a Fellow as graduate work, sometimes by a mem-
ber of the instructional force of the College of Engineering, but
more frequently by an investigator belonging to the Station Corps.
The results of these investigations will be published in the
form of bulletins, and will record mostly the experiments of the
Station's own staff of investigators. There will also be issued
from time to time in the form of circulars, compilations giving
the results of the experiments of engineers, industrial works,
technical institutions and governmental testing departments.
The volume and number at the top of the title page of the
cover refer to the general publications of the University of Illi-
nois; at the bottom is given the number of the Engineering
Experiment Station bulletin or circular.

AN EXTENSION OF THE
DEWEY DECIMAL SYSTEM OF CLASSIFICATION

ENGINEERING INDUSTRIES

and
G. A. GOODENOUGH, ASSOCIATE PROFESSOR OF MECHANICAL ENGINEERING
INTRODUCTION
The decimal system of classification was devised and elabor-
ated by Mr. Melvil Dewey, formerly director of the New York
State Library. This system was intended primarily for the use of
librarians in the classification and arrangement of books and
pamphlets, but it was soon found that the system furnished also
a simple and effective means of classifying, indexing and filing
literary matter of all kinds. Engineers have found it useful for
indexing technical data and information, catalogs, reports, card
systems, drawings, etc., and it has been found equally useful by
manufacturing and business concerns.
Recognizing the value of the decimal system as a means of
classifying and indexing technical literature, the department of
mechanical engineering of the University of Illinois prepared
several years ago an extension of that part of the Dewey classifi-
cation which relates to mechanical engineering. The first edition
was a small pamphlet of six pages. The demand for the extension
was so great that within a year a second edition was printed, and
2 ILLINOIS ENGINEERING EXPERIMENT STATION
this has been followed by the third and fourth editions. In each
successive edition the extension has been carried somewhat fur-
ther, and such slight changes and modifications have been made
as would add to the clearness and consistency of the system as a
whole. In the third edition was incorporated with slight modifi-
cations the extensions for railroads and railroad engineering
adopted by the International Railway Congress.
In this bulletin are included the extensions to mechanical
and railway engineering already worked out; an extension for
electrical engineering made by Mr. J. M. Bryant of the electrical
engineering department; and more or less complete extensions
for other branches of engineering. The whole will be, it is hoped,
a self-contained classification which will cover with fair com-
pleteness the entire ground of engineering industry.
EXPLANATION OF THE DECIMAL SYSTEM
The essential characteristic of the Dewey system is its meth-
od of division and sub-division. The entire field of knowledge is
divided into nine chief classes numbered by the digits from 1 to 9.
Matter of too general a nature to be included in any of these
classes is put into a tenth class and indicated by 0. The follow-
ing are the primary classes of the Dewey system :
General Works
1 Philosophy
2 Religion
3 Sociology
4 Philology
5 Natural Science
6 Useful Arts
8 Fine Arts
8 Literature
9 History
Each of these classes is again divided into nine divisions, with
a tenth division for general matter, and each division is separated
into nine sections. The sections are again sub-divided and the
process may be carried as far as desired.
To show clearly the working of the system the divisions of
class 6 (useful arts) and the sections of division 2 of this class
(engineering) are given.
EXTENSION DECIMAL SYSTEM OF CLASSIFICATION
600 Useful Arts 620 Engineering
610 Medicine 621 Mechanical
620 Engineering 622 Mining
630 Agriculture 623 Military
640 Domestic Economy 624 Bridge and Roof
650 Communication and 625 Road and Railroad
Commerce
660 Chemical Technology 626 Canal
670 Manufactures 627 River and Harbor
680 Mechanic Trades 628 Sanitary: Waterworks
690 Building 629 Other Branches
It will be seen that the first digit gives the class; the second,
the division; and the third, the section. Thus 625 indicates
section 5 (railroad engineering) of division 2 (engineering) of
class 6 (useful arts). For convenience a decimal point is
inserted after the section digit. Further sub-division is indicated
by digits following the decimal point. For example 625.2 is the
number indicating rolling stock; 625.23 passenger cars; 625.24
freight cars, etc.
RELATIVE INDEX
Following the classification is the relative index, in which
the items of the classification are arranged alphabetically, each
with its proper class number. The index is necessarily incom-
plete, as it is manifestly impossible to include every subject that
might arise in engineering practice.
In a highly specialized industry, as for example, the electri-
cal industry, there are thousands of technical terms indicative of
materials and processes and to include these would alone require
a volume. It is believed that the index is sufficiently complete
that the user may without difficulty assign the proper number
to almost any topic that may arise.
In some cases, the same item has two numbers. For example,
"Telephones" has the numbers 537.82 and 654.6. Reference to
the classification shows that the former number is used when the
telephone is considered as an application of the electric current,
while the latter is used when the telephone is looked upon as a
means of communication. In any case, reference to the classifi-
cation will show which number is appropriate to the item under
consideration.

USES AND ADVANTAGES OF THE CLASSIFICATION AND INDEX
The decimal classification may be used to advantage in the
indexing and filing of notes and memoranda, clippings, general
information, articles in technical journals, drawings, catalogs or
books. For this purpose, the decimal system possesses certain
important advantages over the alphabetical system.
(1) It groups allied subjects. For example, suppose the
alphabetical arrangement to be applied to a case of catalogs.
The catalogs of the various machine tools, as planers, lathes,
drills, hammers, etc., would be. scattered throughout the case.
With the decimal system, on the other hand, all these catalogs
would be grouped together under the class number 621.9.
(2) Unless an elaborate system of cross reference is used,
the alphabetical scheme is ambiguous ; in many cases there is
doubt as to what letter should be given a subject. For example,
take the item "Automatic pneumatic block signals." This might
almost equally well be indexed under A, P, B or S. With the
decimal system this item has its one number 656.256.4.
(3) The decimal system has the advantage of flexibility and
an indefinite capacity for extension. For the indexing of books and
catalogs only the main division and sections will, in general, be
found necessary ; but for card indexes of technical literature the
most minute subdivisions must ordinarily be used. In individual
cases, the user may find that still further division is required.
An extension may then be made by adding another decimal place,
and if still further subdivision is required still another digit may
be used.
The average engineer, for example, can easily index all
matter relating to traveling cranes under the single class number
621.872. The designer or builder of cranes may, however, have so
much matter relating to this special subject that further sub-
division is needed. By the addition of a digit, this matter may
be divided into nine groups designated by 621.872.1, 621.872.2, etc. ;
and, if necessary, each of these may be divided into nine new
groups.
The effectiveness of the Dewey system has been severely
tested in the Engineering College of the University. The
mechanical engineering department has a card index of current
periodical literature which now contain 20,000 cards. These are
EXTENSION DECIMAL SYSTEM OF CLASSIFICATION 5
indexed by the Dewey system. The classification is first made
by students, and is then revised by one competent person. It
seldom occurs that there is any doubt as to the proper class num-
ber for a given card. For the guidance of those who may wish to
use the classification in connection with a card index a sample
card is shown on page 8. The class number 621.63 serves to
locate the card in the case and the remaining notes in the margin
indicate the periodical, volume, page and date. Thus the article
in question appeared in the Proceedings of the Institution
of Civil Engineers, Vol. 123, page 272, December, 1895; it
occupies 55 pages and has 31 illustrations.
Blue prints received from manufacturers; all catalogs, of
which there is a large number; clippings, photographs and illus-
trative class room material ; all these are indexed and filed by
the decimal system. In every case the system has been found
thoroughly satisfactory.
VARIATIONS AND MODIFICATIONS
In the working out of- the extension of the various subjects
the main divisions and sections as published by Mr. Dewey have
been retained unchanged. It cannot be denied that there are
many glaring inconsistencies in the arrangement of engineering
subjects. For example, no engineer of to-day wouldi put elec-
trical engineering as a division under mechanical engineering
(621.3) coordinate with blowing and pumping engines (621.6) ;
nor would he relegate concrete to an unimportant place under,
building materials. There is no doubt that a committee of com-
petent engineers could vastly improve the logical arrangement of
the class numbers for engineering subjects. However, the system
as it is, with its faults, has been in use several years and has be-
come more or less universal. It is used in libraries and by many
business concerns and individuals. It has become a sort of a
standard like the Sellers system of screw threads. For this rea-
son alone, radical changes would be inadvisable. The inexperi-
enced user will be likely to see room for improvement and will be
tempted to make changes in the system for his individual use.
Such changes can only lead to confusion. It is far better to accept
the system merely as an arbitrary set of numbers corresponding
to certain topics and resolutely dismiss rigid ideas of logical se-
quence and consistency.
6 ILLINOIS ENGINEERING EXPERIMENT STATION
There are certain permissible modifications, however, which
may be made without violating the integrity of .the system. To
avoid the writing of long numbers a single letter may be used for
the first three or four digits. Thus an electrical engineer would
naturally have most of his material under 621.3 (electrical en-
gineering),, and for this number he could substitute the single
letter E. Likewise, a railroad man might use R for 625 (railroad
engineering).
Another modification consists in the use of an alphabetical
arrangement for certain sub-sections combined with the decimal
arrangement of main sections. This is sometimes useful in
minute subdivisions. For example, under 621.728, material and
supplies for the foundry, these various materials may be arranged
in alphabetical order.
The use of form divisions is a modification that may oflen be
employed to advantage. There are certain set forms that are
used throughout the whole range of the Dewey classification.
These are :
01 Philosophy or theory
02 Oompends, text books, etc.
03 Cyclopedias, dictionaries
04 Essays, addresses
05 Periodicals
06 Societies
07 Education, teaching. Schools, colleges, universities
08 Tables, calculations. Miscellanies
09 History. Progress and development
These forms may be further extended ; thus :
064 Exhibits, etc. (under societies)
072 Laboratories (under universities)
Other form divisions which apply particularly to engineering
are the following:
001 Statistics
002 Quantities and costs
003 Contracts and specifications
004 Designs and drawings
005 Executive
006 Working and maintenance
EXTENSION DECIMAL SYSTEM OP CLASSIFICATION . 7
007 Laws
008 Patents
009 Keports
These form divisions may be enclosed in parentheses and an-
nexed directly to the usual class number. Thus 62(07) indicates
engineering education ; 621.32(09), progress of electric lighting;
621.57(008), patents on ice-making machinery, etc. The object
of this parenthesis separation of the form divisions is convenience
in cross-references. For example if one is interested in patents
he may write his class numbers as follows :
(008)62 Patents Engineering
(008)66 Patents Chemical technology
(008)69 Patents Building
In this way all cards on patents are grouped together.
Other modifications will suggest themselves to the user as he
becomes more familiar with the system.
