An Extension 

of the 

Dewey System of Classification 

as applied to 

Mining 



By CARL A. ALLEN, E. M. 

Assistant Professor of Mining 

Colorado School of Mines 



INTRODUCTION. 

A serious problem that confronts every engineer is how to 
make most available that mass of information to which he must 
constantly refer. Probably of all the engineers, he who follows 
mining has the most widely varying problems to solve. Each 
new one that presents itself requires thorough study and the 
bringing to* bear upon 1 it of all the data that can be found. If 
a mining engineer is called upon to report on a mine, he will be 
aided if he can find descriptions written by some previous in- 
vestigator. Too often, however, the information that is wanted 
is just the information that cannot be found. Public and private 
libraries have on their sh-elves an enormous amount of material 
that should be available with the least loss of time. Many 
methods of indexing have been used, based often on alphabetical 
order. The trouble with an alphabetical arrangement is that it 
is difficult to pick from the titles of many books the word the 
initial letter of \vhich should determine its place in the alpha- 
betical list. With an alphabetical shelf arrangement, a book on 

245458 






SCHOOL OF MINES. 

''Child Study" might come next to one on "Chilian Mills," and 
one on "Grinding Machines" would be placed considerably 
farther along. To overcome these difficulties, most libraries now 
use what is known as the "Decimal Classification and Relative 
Index," called the "Dewey Decimal System." As its name indi- 
cates, this system is a numerical one. Each subject is given a 
number, and the shelf arrangement, being by number, brings 
similar subjects together. All knowledge that is, we might 
say, all reading matter is divided into ten classes, as follows : 

General Works. 

1 Philosophy. 

2 Religion. 

3 Sociology. 

4 Philology. 

5 Natural Science. 

6 Useful Arts. 

7 Fine Arts. 

8 Literature. 

9 History. 

These classes are divided into divisions. Number 6, or 
''Useful Arts," is subdivided as follows : 

610. Medicine. 

620. Engineering. 
630. Agriculture. 

640. Domestic Economy. 

650. Communication and Commerce. 

660. Chemical Technology. 

670. Manufactures. 

680. Mechanic Trades. 

690. Building. 

These divisions are again subdivided into sections, and num- 
ber 620, or "Engineering," is divided as follows : 

621. Mechanical Engineering. 

622. Mining Engineering. 

623. Military. 

624. Bridge and Roof. 

625. Road and Railroad. 

626. Canal. 

627. River and Harbor..

: 628. Sanitary. Water Works. 
629. Other Branches. 

"Mining Engineering" has the number 622, and books or 
articles numbered 622 would be placed on the shelf between those 
numbered 621 and those numbered 623. As can readily be seen, 
this subdivision can be carried as far as desired. In the original 
classification it was carried to five figures, as is given on page, 
ir, and for a general library this is sufficient. For the library 
of a mining man, however, it is not enough. For example, it 
will be noted that 622.69 is "Surface Transportation." The 
average mining engineer will accumulate too many articles that 
would be classed under "Surface Transportation," but yet would 
be different; as, for instance, "Aerial Tramways" and "Wagon 
Roads." Hence, a further extension or subdivision is necessary, 
and this extension has been carried out in this bulletin. 

The principle of the system has been explained in order 
that a better understanding of its application may be gained. 
Never was there the wealth of valuable information to be found 
in technical books and periodicals as at the present time. Every 
engineer must have some system of making available the infor- 
mation that he may want at any time, and the "Dewey System" 
is probably the only scheme that has stood the test. At the Uni- 
versity of Illinois the effectiveness of the system has been tried 
in the Engineering College and has been found thoroughly satis- 
factory. If engineers will take the small amount of trouble 
necessary to become familiar with the system they will find it 
well adopted to their needs, and it will make available a large 
amount of technical literature that would otherwise be lost. 

APPLICATION OF THE SYSTEM. 

There are three ways in which the classification may be used 
by engineers. First, by a card index ; second, in filing articles 
and clippings without an index; and, third, in a combination of 
the two or filing away the material according to the' decimal 
system, with a card index arranged either alphabetically or ac- 
cording to the "Dewey System." As to which of the three ways 
is best, opinions differ; also, it depends on the extent of the 
material to be indexed. 

CARD INDEX. 

Many engineers use a card index arranged alphabetically. 
If they notice an article on "Sinking and Timbering Shafts," they 



6 THE COLORADO SCHOOL OF MINES. 

make out two cards, stating" the title, length and perhaps the 
character of the article and where it may be found. One of these 
cards will be placed in the drawer under "S" for "Shaft Sinking," 
and one under "T" for "Timbering." The only difference, if the 
decimal system of arrangement is employed, is that the cards, 
after being made out, would be given proper numbers and, placed 
in the drawer in their numerical order, would thus avoid the 
weakness of any alphabetical arrangement. 

The card index finds its best application when the user has 
in his office only a few of the articles to which referenece is 
made. The objections to it are two : First, there is usually 
trouble in finding- the magazine in which the article occurs, and, 
if the amount of material is large, the card index alone would 
not be sufficient. Second, many engineers will not keep up a 
card index. This is without doubt the most serious objection. 
Its beneficial use and general adoption by large business con- 
cerns has led many to believe that the card index alone is a 
"panacea for all ills," but they should remember that these con- 
cerns have competent and sufficient clerical help to keep the cards 
up to date, an advantage which many engineers do not enjoy. 

FILING MATERIAL WITHOUT AN INDEX. 

As to the second way of using the classification that is, 
for filing information without an index the following descrip- 
tion of its adoption at the Colorado School of Mines will prob- 
ably serve best to enable the reader to judge if it is applicable 
to his requirements. The mining department has a case con- 
taining a large number of pigeon holes 5" wide, 12" high and 
14" deep, which are numbered according to the Dewey System, 
622.11, 622.12, etc. When a new copy of the "Engineering and 
Mining Journal" arrives it is read and then, by removing the 
binding clips, the different articles it contains are taken out and 
placed in their proper pigeon holes. That is, if there be an 
article on "Timbering," it will be placed in number 622.2 along 
with articles on "Timbering" that may be taken from "Mines and 
Minerals," "Mining and Scientific Press," or "Mining Science." 
Then when any information is desired on "Timbering," by going 
to that pigeon hole we have all the latest information together. 
If the 1 number of articles in the pigeon hole becomes great, they 
are divided into their proper classes and placed in large envelopes 
with the proper number on the outside. That is, envelope' num- 
bered 622.281 would contain all the articles on "Kinds and 



THE COLORADO SCHOOL OP MINES. 7 

Properties of Timber for Mine Use." If crowded for room, 
envelopes could be used entirely, arranged in large drawers or 
otherwise. Where an article might be classed under two head- 
ings, it is placed where it has the most weight, and, if desired, 
a reference to it on a blank sheet in the other pigeon hole can 
be made. Also on the. blank sheet can be written references to 
articles occurring in some book or paper which may be found 
only in the library. As most strong articles occur in at least 
two of the mining papers, very little cross referencing has been 
found necessary. The article taken from one magazine is put 
in one place, and from the other magazine in the other place. 
This also often prevents losing one article, because part of it is 
on the same sheet with another article, and, of course, the same 
results would be secured by having more than one copy of the 
same paper. Two advantages of the method are worthy of 
mention : First, the articles are immediately available, and, 
second, in case it is desired to take the information on a trip, it 
can be done without having to take a complete bound volume. 

BOTH CARD INDEX AND FILING. 

The third way of using the "Dewey System" is really a com- 
bination. Books and magazines are placed on the shelves in 
their proper order numerically and a card index is maintained 
referring to subjects to be found on the shelves or elsewhere. 
Where there are many books and the- mass of material is large, 
this is to be recommended. It is the method used in libraries 
where only the card index is alphabetical for the use of the 
public. 

EXTENSION OF THE CLASSIFICATION. 

In extending the classification, the aim has been towards 
as logical a subdivision as possible. The original classification, 
although imperfect, has not been changed. This is because oi 
the copyright restrictions; also, because of the reverence for 
the master mind that evolved the entire subdivision of all knowl- 
edge. The imperfections can be seen in the subdivision of 
"Drainage," but to attempt to chan.ee it would be inadvisable, be- 
cause so many have already adopted it. The original subdivision 
is printed separately, so that it may be torn out and posted near 
the filing case. For placing many articles this will suffice and 
will save many references to the extended classification. 

In order to cover the ground of mining fully it was neces- 
sary to go into Geology and Mechanical Engineering, and the 



8 THE COLORADO SCHOOL OF MINES. 

subjects coming under those divisions that are found in the min- 
ing engineer's library) have been put in. Those on Mechanical 
Engineering were taken from Bulletin No. 9 of the University 
of Illinois, which is an extension of that subject. Nothing has 
been put in on Metallurgy and Assaying. A bulletin covering 
the extension on these subjects has already been issued by the 
Colorado School of Mines, and copies may be obtained from 
the President of the school. 

FORM DISTINCTIONS. 

In the application of the "Dewey System" it has been found 
useful to employ a series of form distinctions or divisions. The 
literature of any subject may often be advantageously separated 
into these subdivisions, which are as follows : 

.001. Statistics. . 

.002. Quantities and costs. 

.003. Contracts and specifications. 

.004. Designs and drawings. Maps. 

.005. Executive. 

.006. Working and maintenance. 

.007. Laws. 

.008. Patents. Machinery. 

.009. Reports. 

.01. Philosophy or theory. 

.02. Compends. Indices. Directories. 

.03. Cyclopedias. Dictionaries. 

.04. Essays. Address. Letters. Theses. 

.05. Periodicals. Magazines. 

.06. Societies. 

.07. Education. Study and teaching. 

.08. Tables and calculations. 

.09. History. Progress and development. 

These form distinctions may be used not only to subdivide 
general subjects, as is done for 622 on page 25, but they can 
also be used for the minor subdivisions, as, for example, 
622.141.09 would be the history of mine surveying instruments. 

ALPHABETICAL SUBDIVISION. 

The use of an alphabetical arrangement for minute sub- 
divisions may sometimes be used to advantage, as has been done 
for mines and mining districts on page 33. This is by no 



THE COLORADO SCHOOL OF MINES. g 

means an alteration of the Dewey System, but one that is indi- 
cated in his book, and for this particular case is the only logical 
arrangement. 

RELATIVE INDEX. 

The second part of the bulletin consists of the relative in- 
dex, which is merely a finding list where the subjects or headings 
are arranged alphabetically and the proper number is given. The 
placing of a period after every three figures in a number is 
simply for convenience in reading. The first three figures for 
mining engineering are always 622, and may be replaced by a 
letter or sign if desired..
