SCHOOl / / Quarterly of the Colorado School of Mines Vol. 6 April, 1911 No. 1 An Extension of the Dewey System or Classmcation Applied to Metallurgy, Metallograpny ana Assaying ROBERT M. KEENEY Fellow in Metallurgy COLORADO School of Mines The rapid growth of metallurgical industries has rendered necessary a more complete system of classification of the literature on this subject than is afforded by the Dewey classification. The most complete extension, covering all engineering as well as metal- lurgical subjects, is found in Bulletin ISTo. 9, issued in ISTovember, 1906, by the Engineering Experiment Station of the University of Illinois. In this bulletin the extensions relating to mechanical, electrical, and railway engineeriug are complete, but the other branches are incomplete. The extension herein given has been prepared to cover this deficiency in metallurgy, metallography, and assaying. 245526 4 THE COLORADO SCHOOL OF MINES. In the Dewey decimal system the entire field of knowledge is divided into ten main classes, nnmbered l)y the digits from to 9. The primary classes are General Works. 1 Philosophy. Religion. o O Sociology. 4 Philology. 5 ]*»J'atnral Science, 6 Usefnl Arts. 7 Fine Arts. 8 Literature. 9 History. Each of these classes is similarly divided into ten divisions. The divisions are divided into ten sections, and the process is re- peated as often as is necessary. Thus 669 means Class 6 (Useful Arts), Division 6 (Chemical Technology), and Section 9 (Metal- lurgy). In carrying the system out, a decimal point is ]ihiced for convenience after every third digit. To illustrate further, con- sider 669.145.412 (Bessemer Converter Tuyeres) ; 669 as already explained means Metallurgy; 669.1, the Metallurgy of Iron and Steel; 669.14, the Manufacture of Steel; 669.145, the Bessemer Process for Steel Manufacture; 669.145.4, the Bessemer Con- verter; and 669.145.41, the Construction of the Bessemer Con- verter; and 669.145.412, Bessemer Converter Tuyeres. The table of numbers is followed by a relative index in which each table title is arranged alphabetically with its ]:)roper number. It is clearly impossible to include all the terms con- nected with metallurgy, metallngraphy, and assaying in this index, but enough are given to enable the user to assign the pro]ioi' num- ber to almost any subject that may arise. The relative index is very useful to the person in search of information indexed l)y this system, in that it shows at once the various numbers under wliieh an item occurs in cnse it has more than one number. For exam- ple: roasting of arsenical ores ii jdaccMl under 669.22. un(h'r 669.32, and under 669.42. THE COLORADO SCHOOL OF MINES. 5 In the present extension of the system the main subdivisions under 669 have been left unchanged with the exceptions, that use is made of the digit (0), by making 669.0, General Metallurgy, which includes fuels, furnaces, and refractories, and that under 669.8 is placed metallography, a branch of metallurgy which is growing rapidly and is so closely allied to it that it should be classed near metallurgy. These changes are thought advisable, as 669 (Metallurgy) has not been sufficiently extended to cause con- fusion. The character (0) has been used throughout this classifi- cation as any other digit, for, although after a decimal point, it does not increase the number numerically, yet it acts as a distinct- ive symbol. All items pertaining to ore dressing, except in a gen- eral way, are excluded, as ore dressing is classed under 622 (Min- ing). The general forms of the Dewey classification have been modified to suit the subject, and where it seems desirable they are stated in full. An elaborate system of cross reference does not seem necessary, as the relative index shows where an item should be placed. For a person keeping an index on the subjects of metallurgy, metallography, and assaying, and not too many other subjects, it is convenient to substitute a letter for the first three digits, thus for 669 (metallurgy, metallogTaphy, and assaying) the letter M. In making small subdivisions it is sometimes convenient to arrange the subjects in alphabetical order, giving a combination of the decimal with the alphabetical system. For the benefit of persons who wish to extend the system for their own use, blank spaces have been left where it seems advisable. The decimal system of classification is adapted to the index- ing of books, notes, clippings from journals, drawings and cata- logues. In libraries, books and pamphlets may be filed according to the system with an alphabetical card index showing under what numbed the book sought is to he found. In indexing current tech- nical literature, where the number of cards becomes large, it will be found convenient to keep the card index in order of the num- bers of the decimal system rather than by alphabetical order. Engineers can use the system in three ways: first, to keep THE COLORADO HCHOOL OF MINES. a card index of technical literature; second, to file clippings from journals, notes, drawings and catalogues, without a card index ; or, third, for a combination of the card index with the filing system, so that a reference to a journal of which there is no clipping at hand can be recorded with other references. In filing clippings, an envelope, 7% inches long and 514 inches wide, is a convenient size. The spacing for recording may be arranged as indicated on the type form given below. Articles under a sub'livision may he filed in alphabetical order. Subject. 1 No. Notes. 669.147 A New Process for Refining of Pig M. & C. E. Iron. V. 9 p. 121 (3 p.) f. B.

THE COLORADO SCHOOL OF MINES. 7 ABBREVIATIONS USED ON INDEX CARDS Pages p Diagrams, sketches, etc d Curves, plots, or groups of same c Illustrations, photographs, etc i Tables of data, etc t Words w Volume V The index card refers to an aiticle which appeared in Metal- lurgical and Chemical Engineering, Vol. 9, page 127, March, 1911, and occupies three pages, with no illustrations. The class number 669.147 serves to locate the card in the case of the index. The decimal system possesses several very important advan- tages over the alphabetical system : lirst, it groups allied sub- jects which, under the alphabetical arrangement, would be widely scattered ; second, under the alphabetical system there are many cases in which it is difficult to determine wdiat letter to assign to a subject, and much confusion results, all of which is avoided in the decimal system ; and third, in the decimal system there is great flexibilitv and room for extension.
