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 of Mathematics is 510, not 503, for every book is assigned to the most specific head that will contain it, so that 503 is limited to Dictionaries or Cyclopedias of Science in general. In the same way a General Cyclopedia or Periodical treats of no one class, and so is assigned to the Class 0. These books treating of no special class, but general in their character, are divided into Cyclopedias, Periodicals, etc. No difficulty is found in following the arithmetical law and omitting the initial zero, so these numbers are printed 31, 32, etc., instead of 031, 032, etc.
The selection and arrangement of the thousand headings of the classification cannot be explained in detail for want of space. In all the work, philosophical theory and accuracy have been made to yield to practical usefulness. The impossibility of making a satisfactory classification of all knowledge as preserved in books, has been appreciated from the first, and nothing of the kind attempted. Theoretical harmony and exactness has been repeatedly sacrificed to the practical requirements of the library or to the convenience of the department in the college. As in every scheme, many minor subjects have been put under general heads to which they do not strictly belong. In some cases these headings have been printed in a distinctive type, e. g., 429 Anglo-Saxon, under ENGLISH PHILOLOGY. The rule has been to assign these subjects to the most nearly allied heads, or where it was thought they would be most useful. The only alternative was to omit them altogether. If any such omission occurs, it is unintentional and will be supplied as soon as discovered. Wherever practicable the heads have been so arranged that each subject is preceded and followed by the most nearly allied subjects and thus the greatest convenience is secured both in the catalogues and on the shelves. Theoretically, the division of every subject into just nine heads is absurd. Practically, it is desirable that the classification be as minute as possible without the use of additional figures, and the decimal principle on which our scheme hinges allows nine divisions as readily as a less number. This principle has proved wholly satisfactory in practice though it appears to destroy proper co-ordination in some places. It has seemed best in our library to use uniformly three figures in the class number. This enables us to classify certain subjects very minutely, giving, for example, an entire section to Chess. But the History of England has only one section, as our scheme is developed, and thus the two might be said to be co-ordinated. The apparent difficulty in such cases is entirely obviated by the use of a fourth figure, giving nine sub-sections to any subject of sufficient importance to warrant closer classification. In history where the classification is made wholly by countries, a fourth figure is added to give a division into periods. As the addition of each figure gives a ten-fold division, any desired degree of minuteness may be secured in the classing of special subjects. The apparent lack of co-ordination arises from the fact that only the first three figures of these more important heads are as yet printed, the fourth figure and the sub-sections being supplied on the catalogues in manuscript. Should the growth of any of these sub-sections warrant it, a fifth figure will be added, for the scheme admits of expansion without limit.
The arrangement of headings has been sometimes modified to secure a mnemonic aid in numbering and finding books without the Index. For instance, the scheme is so arranged that China has always the number 1. In Ancient History, it has the first section, 931: in Modern History, under Asia, it has 951: in Philology, the Chinese language appears as 491. After the same manner the Indian number is 2; Egyptian, 4; English, 2; German, 3; French, 4; Italian, 5; Spanish, 6; European, 4; Asian, 5; African, 6; North American, 7; South American, 8; and so for all the divisions by languages or countries. The Italian 5, for instance, will be noticed in 35, 55, 450, 755, 850, and 945. This mnemonic principle is specially prominent in Philology and Literature and their divisions, and in the form distinctions used in the first 9 sections of each class. Materials, Methods, or Theory occurring anywhere as a head, bears always the number 1. Dictionaries and Cyclopedias, 3; Essays, 4; Periodicals, 5; Associations, Institutions, and Societies, 6; Education, 7; Collections, 9. In the numerous cases where several minor heads have been grouped together under the head Other, it always bears the number 9. Wherever practicable, this principle is carried out in sub-dividing the sections. For instance, the Geology of North America, which bears the number 557 is sub-divided by adding the sections of 970 (History of North America). The Geology of Mexico then bears the number 5578: mnemonically, the first 5 is the Science number; the second 5, Geology; the 7, North America; and the 8, Mexico. Any library attendant or reader after using the scheme a short time will recognize at a glance, any catalogue or ledger entry, book or pamphlet, marked 5578 as something on the Geology of Mexico. Users of the scheme will notice this mnemonic principle in several hundred places in the classification, and will find it of great practical utility in numbering and finding books without the aid of Catalogue or Index, and in determining the character of any book simply from its call number as recorded on the book, on all its catalogue and cross reference cards, on the ledger, and in the check box.
In naming the headings, brevity has been secured in many cases at the sacrifice of exactness. It was thought more important to have short, familiar titles for the headings than that the names given should express with fullness and exactness the character of all books catalogued under them. Many subjects, apparently omitted, will be found in the Index, assigned, with allied subjects, to a heading which bears the name of the most important only. Reference to this Subject Index will decide at once any doubtful points.
In arranging books in the classification, as in filling out the scheme, practical usefulness has been esteemed the most important thing. The effort has been to put each book under the subject to the student of which it would be most useful. The content or the real subject of which a book treats, and not the form or the accidental wording of the title, determines its place. Following this rule, a Philosophy of Art is put with Art, not with Philosophy; a History of Mathematics, with Mathematics, not with History; for the philosophy and history are simply the form which these books have taken. The true content or subject is Art, and Mathematics, and to the student of these subjects they are most useful. The predominant tendency or obvious purpose of the book, usually decides its class number at once; still many books treat of two or more different subjects, and in such cases it is assigned to the place where it will be most useful, and underneath the class number are written the numbers of any other subjects on which it also treats. These Cross References are given both on the plate and the subject card as well as on the cross reference card. If a book treats of a majority of the sections of any division, it is given the Division number instead of the most important Section number with cross references.
Collected works, libraries, etc., are either kept together and assigned like individual books to the most specific head that will contain them; or assigned to the most prominent of the various subjects on which they treat with cross references from the others; or are separated and the parts classed as independent works. Translations are classed with their originals.
The Alphabetical Subject Index is designed to guide, both in numbering and in finding the books. In numbering, the most specific head that will contain the book having been determined, reference to that head in the Index will give the class number to which it should be assigned. In finding books on any given subject, reference to the Index will give the number under which they are to be sought on the shelves, in the Shelf Catalogue, or in the Subject Catalogue. The Index gives after each subject the number of the class to which it is assigned. Most names of countries, towns, animals, plants, minerals, diseases, &c, have been omitted, the aim being to furnish an Index of Subjects on which books are written, and not a Gazetteer or a Dictionary of all the nouns in the language. Such subjects will be found as special chapters or sections of books on the subjects given in the Index. The names of individual subjects of biographies will be found in the Class List of Biography. Omissions of any of the more general subjects will be supplied when brought to notice.
In arranging the books on the shelves, the absolute location by shelf and book number is wholly abandoned, the relative location by class and book number being one of the most valuable features of the plan. The class number serves also as the location number and the shelf number in common use is entirely dispensed with. Accompanying the class number is the book number, which prevents confusion of different books on the same subject. Thus the first Geometry catalogued is marked 513-1; the second 513-2, and so on to any extent, the last number showing how many books the library has on that subject. The books of each section are all together, and arranged by book numbers, and these sections are also arranged in simple numerical order throughout the library. The call number 513-11 signifies not the 11th book on shelf 513; or alcove 5, range 1, shelf 3, as in most libraries, but signifies the 11th book in subject 513 or the 11th Geometry belonging to the library. In finding the book, the printed numbers on the backs are followed, the upper being the class and the lower the book number. The class is found in its numerical order among the classes as the shelf is found in the ordinary system: the book in its numerical order in the class. The shelves are not numbered, as the increase of different departments, the opening of new rooms, and any arrangement of classes to bring the books most circulated nearest to the delivery desk, will bring different class numbers on a given shelf. New books as received are numbered and put into place, in the same way that new titles are added to the card catalogue.
The single digit occasionally prefixed to the book number, e.g. the 3 in 421-3-7 is the nearest height in decimeters of books too large to be put on the regular library shelves, which are only 2½ decimeters apart. The great mass of the library consists of 2-decimeter books, the size numbers of which are omitted. Books from 2½ to 3½ decimeters in height have 3 prefixed to the book number, and are found on the bottom shelf of each range. The larger sizes are prefixed with 4, 5, &c., and are found on the special shelves provided, in order to avoid the great waste of space otherwise occasioned by the relative location. By this use of the size numbers a close economy of space is secured.
Thus all the books on any given subject are found standing together, and no additions or changes ever separate them. Not only are all the books on the subject sought, found together, but the most nearly allied subjects precede and follow, they in turn being preceded and followed by other allied subjects as far as practicable. Readers not having access to the shelves find the short titles arranged in the same order on the Shelf Catalogue, and the full titles, imprints, cross references, notes, &c., on the Subject Catalogue. The uncatalogued pamphlets treating of any subject bear the same class number and are arranged on the shelves immediately after the books of each section.
In both the Authors' Catalogue and the Subject Index, brevity has been studied because of the economy, but more because of the much greater ease of reference to a short title catalogue. The custom of giving full titles, etc., under authors, and only references or very brief titles under subjects, has been reversed. A reader seeking a book of a known author, in the vast majority of cases, wants simply the number by which to call for it, and can find it much sooner in a brief title catalogue. In the rare cases where more is needed the class number refers instantly to all these facts on the cards. On the other hand, a reader seeking books on a known subject, needs the full title, imprint, cross-references, and notes, to enable him to choose the book best suited to his wants.
The Subject Catalogue is a full title Shelf List on cards and is for the use of the public. The Shelf List is a short title Subject Catalogue in book form, made of separate sheets laced into an Emerson binder, and is for official use. We thus have without extra labor, both full and short title Subject Catalogues and Shelf Lists. The public Authors' Catalogue is a printed volume; the official Authors' Catalogue or Index is on cards. As a result each of the public Catalogues is checked by an official Catalogue; each of the card Catalogues by a book Catalogue; each of the brief title catalogues by a full title catalogue--an advantage that will be appreciated by all librarians desiring accuracy of administration and catalogues.
The Arabic numerals can be written and found more quickly, and with less danger of confusion or mistake, than any other symbols whatever. Therefore the Roman numerals, capitals and small letters, and similar symbols usually found in systems of classification are entirely discarded and by the exclusive use of Arabic numerals in their regular order throughout the shelves, classifications, indexes, catalogues and records, there is secured the greatest accuracy, economy, and convenience. This advantage is specially prominent in comparison with systems where the name of the author or the title must be written in calling for or charging books and in making references.
Throughout the catalogues the number of a book shows not only where it is but what it is. On the library accounts the character of each person's reading is clearly indicated by the numbers charged, and the minutest statistics of circulation in any subject are made by simply counting the call slips in the check box, and recording the number against the class number in the record.
By the use of size numbers the greatest possible economy of space may be secured, for the size distinction may be made for every inch or even less if desired, and this without additional labor, as it will be seen that the size figure, when introduced, requires one less figure in the book number, and so does not increase the number of digits as would at first appear.
Parts of sets, and books on the same or allied subjects, are never separated as they are sure to be, sooner or later, in every library arranged on the common plan, unless it be frequently re-arranged and re-catalogued. The great expense of this re-cataloguing makes it impracticable except for a few very wealthy libraries. In this system the catalogue and book numbers remain unchanged through all changes of shelving, buildings, or arrangement. In addition to its own peculiar merits, this plan has all the advantages of the card catalogue principle and of the relative location, which have been used and very strongly approved by prominent libraries.
As in the card catalogue system, there is room for indefinite expansion without devices or provisions. Space is the only requisite and if the shelf room is exhausted, the floor space is equally good, except for the inconvenience of stooping.
Some prominent opponents of classed catalogues have admitted that the Subject Index, in deciding where to class a book at first, and where to look for it ever afterwards, has removed their strongest objections. Certainly it would be impossible to make an Index more cheaply or more easy of reference, it being a single alphabet, of single words, followed by single numbers.
These class numbers applied to pamphlets have proved specially satisfactory. The number is written on the upper left corner and the pamphlets are arranged either in pamphlet cases with the books on the same subject or on special shelves divided every decimeter by perpendicular sections. As each pamphlet is examined when received into the library, it is the work of a single moment to pencil on it its class number. There is no expense whatever incurred, and yet the entire pamphlet resources of the library on any subject can be produced almost instantly. The immense advantages of this plan over those in common use, both in economy and usefulness, will be appreciated by every librarian caring for a pamphlet collection. A catalogue of authors may be made on slips if desired. The pamphlets themselves are the best Subject Catalogue.
Though designed wholly for library use, the plan has proved of great service in preserving newspaper clippings in large envelopes arranged by class numbers; and more especially in taking the place of the common note-book and Index Rerum. Slips of uniform size are used with the class number of the subject written on the corner. Minute alphabetical headings are used under each class number, the slips being arranged in numerical order like the Subject Card Catalogue. Clippings and notes arranged in this way are at all times their own complete index, and have the same advantages over the common scrap and note-books that the Subject Catalogue has over the Accessions Book, in looking up the resources of the library on any given subject. Those who have tried this method are so enthusiastic in its praise that it seemed worthy of mention in this place.
The plan was adopted in the Amherst College Library in 1873, and the work of transferring the entire library to the new catalogue at once commenced. It was found entirely practicable to make the change gradually, as means allowed, without interfering in any appreciable degree with the circulation of the books. The three years trial to which it has been there subjected has more than justified the claims of its friends, and it is now printed with the more confidence on this account. It has been kept in manuscript up to this time, in order that the many minor details might be subjected to actual trial and modified where improvement was possible. The labor involved in preparing the Classification and Index has been wholly beyond the appreciation of any who have never attempted a similar task. Much valuable aid has been rendered by specialists in many departments, and nearly every member of the Faculty has given advice from time to time. Among the many to whom thanks are due, special mention should be made of Mr. C.A. Cutter, the librarian of the Boston Athenæum, and Mr. John Fiske, of the Harvard University library, for valuable suggestions and appreciative criticism. While these friends are in no way responsible for any remaining imperfections in the scheme, they should have credit for many improvements which have been made during these three years of revision. The essential character of the plan has remained unchanged from the first. Doubtless other improvements are still possible, and it is hoped that users of the scheme will call attention to any proposed change in the naming or arrangement of the headings, or to any omission which should be supplied in the Subject Index.
Before printing, the plan was submitted to quite a number of librarians for criticism. Among the hundreds of points raised as to its practical workings and usefulness there was only one in which it was not shown to be equal or superior to any other system known. This objection applied only to the arrangement on the shelves; not at all to the catalogues or indexes. It was, that in this relative location, a book which this year stands, e.g., at the end of a certain shelf; may not be on that shelf at all another year, because of the uneven growth of the parts of the library. This slight objection inheres in any system where the books are arranged by subjects rather than by windows, doors, shelves, and similar non-intellectual distinctions.
In this hurriedly prepared account of his plan, the author has doubtless failed to meet many objections which may be raised and which he could easily answer. He would therefore ask the privilege of replying personally to any such objections, where they arise, believing that it will be possible to answer, if not all, at least a very large proportion.
In his varied reading, correspondence, and conversation on the subject, the
author doubtless received suggestions and gained ideas which it is now impossible
for him to acknowledge. Perhaps the most fruitful source of ideas was the Nuovo
Sistema di Catalogo Bibliografico Generale of Natale Battezzati, of Milan. Certainly
he is indebted to this system adopted by the Italian publishers in 1871, though he
has copied nothing from it. The plan of the St. Louis Public School Library,
and that of the Apprentices' Library of New York, which in some respects resemble
his own, were not seen till all the essential features were decided upon, though
not given to the public. In filling the nine classes of the scheme the inverted
Baconian arrangement of the St. Louis Library has been followed. The author
has no desire to claim original invention for any part of his system where another
has been before him, and would most gladly make specific acknowledgment of
every aid and suggestion were it in his power to do so. With these general
explanations and acknowledgments he submits the scheme, hoping it may prove
as useful to others as it has to himself.

The titles of the subject catalogue are exact transcriptions of the title page, neither amended, translated, or in any way altered, except that mottoes, titles of authors, repetitions, or matter of any kind not essential to a clear titular description, are omitted. Omissions of mottoes are indicated by three stars (* * *); of other matter by three dots (...). The phraseology, spelling, and punctuation of the title are exactly copied; but capitals are given only to proper names and adjectives, and initial words of sentences. Any additions needed to make the title clear are supplied and enclosed by brackets.
After the titles, are given in order: the place of publication; the year; the year of copyright, if different, in brackets; the edition; the number of volumes, or of pages if in only one volume; the illustrations, maps, plates, or portraits; and the size nearest in the arbitrary scale, regardless of the fold of the sheet. This scale gives the heights in decimeters. Square and oblong books have the size prefixed by sq. or ob. Books 1 decimeter high are called 32°; 1.5 deci., 16°; 2 deci., 12°; 2.5 deci., 8°; 3 deci., 4°; and all others are marked simply by the nearest height, i.e. a book marked 4 is between 3.5 and 4.5 decimeters high. In books having more than one pagination the number of pages is indicated by giving the last number of each pagination connected by a +; an added + indicates additional matter unpaged.
These imprint entries give the facts regardless of the title page, and are left blank only when they can be ascertained neither from the book itself or other sources.
The contents of volumes are given when on title pages, or when necessary to properly identify the volume, but no analysis is attempted. Necessary notes are given at the bottom of the subject card after the imprint entries.
Duplicates are simply marked copy 2, copy 3, etc., and bear the same class and book number, but editions of the same book distinct in character are catalogued separately.
In all the catalogues, books are entered under the surnames of authors when known; under the initials of author's names, when these only appear, the last initial being put first; under the pseudonyms of the writers, when the real names are not ascertained; under the names of editors of collections; under the names of countries, cities, societies, or other bodies which are responsible for their publication; under the first word not an article of the titles of periodicals and of anonymous books the names of whose authors are not ascertained. Commentaries with the text, and translations are entered under the heading of the original work, but commentaries without the text are entered under the name of the commentator. The Bible or any part of it in any language is entered under the word Bible. Books having more than one author are entered under the first named on the title.
In the headings of titles, the names of authors are given in their vernacular form. In English and French surnames beginning with a prefix (except the French de and d') the name is recorded under the prefix. In other languages and in French names beginning with de and d', the name is recorded under the word following the prefix. Compound surnames are entered under the first part of the name. Noblemen and ecclesiastical dignitaries are entered under their family names, but sovereigns, princes, oriental writers, friars, persons canonized, and all other persons known only by their first name, are entered under this first name.
The catalogue is not a biographical dictionary, so only gives the names of authors with sufficient fullness to distinguish them from each other in practical use.
Names in full face type are the ruling headings under which the books are entered in the various catalogues. Entries not beginning with this type are in addition to the first or main entry, and are made under the names of translators, editors, commentators, continuators, etc., as participators in the authorship; also in the case of books having more than one author, or having both generic and specific titles, or published by societies or other bodies, and having also the name of the individual author. These additional entries are made in order to carry out the plan of the Authors' Catalogue, which aims to give under each author's name all his works which the library contains.
The works of an author known by more than one name are given all together, under the form of name chosen. Any other name or title by which he may be known, if it differs in the first three letters, is entered in its alphabetical place, followed by the word see and the name under which the books are entered. Such cross references have no titles given under them, but are simply guides to the name chosen.
A single dash indicates the omission of the preceding heading; a subsequent dash indicates the omission of a subordinate heading or of a title. A dash connecting numbers signifies to and including; following a number it signifies continuation. A ? following a word or entry signifies probably. Brackets enclose words added to titles or changed in form.
The German diphthongs ä, ö, ü are written, ae, oe, ue.
Dates are all given in years of the common calendar, and Arabic numerals are uniformly used for all numbers.
The Subject Catalogue on large cards can be used to advantage only with the aid of the Classification or Index. To find what the library has on any given subject, get from the Index the class number of that subject. Under this number in the Subject Catalogue will be found the full titles of the books, with imprints, cross references, and notes. The class number, by which the cards are arranged, is given in the upper left corner and immediately under it is the book number. Any other class number given in the left hand margin refers to another subject of which the book also treats. When the class number at the top is followed by an additional figure in brackets, the subject as given in the printed scheme has been subdivided in arranging the cards. This subdivision will be found on the first card of the catalogue which bears this class number. These figures in brackets determine the arrangement of the titles in the Catalogue, but on the shelves, in the Shelf Catalogue, and in calling for and charging books, they are entirely disregarded. Thus a book numbered 942(7).14 would be in the Catalogue among the 942 cards arranged by the figure in brackets as though it were a decimal, but it would be called for as 942.14, the brackets indicating that the final classing was limited to the Catalogue and was not extended to the shelves. If a fourth figure is added without brackets, the final classing is extended to the shelves as well as to the catalogue, and all the figures must be used in calling for the book. In such cases the added figure is treated as a decimal in the arrangement, though the decimal point is not written.
The last card which bears any class number, gives under that number, followed by the word SEE the call numbers of other books which treat of the same subject, but are classed elsewhere. General cross references are also made in many cases without specifying individual books, as from Commerce as a question of SOCIAL SCIENCE (380) to Commerce as a USEFUL ART, Book-keeping Business Manuals, etc. (650). In such cases there is a card under 380 marked SEE 650, and under 650 there is a card marked SEE 380. From whatever stand-point a subject is approached, the cross references guide at once to the same subject treated in its other relations. These cross references both general and specific are often accompanied by brief notes, characterizing the books to which reference is made.
There will be found at the beginning of many class numbers, a card noting the most reliable books on that subject, and the best of the articles in periodicals, transactions, and collected works with the volume and page where they may be found. It is hoped to give special prominence to these notes for the guidance of readers, and they will be added as rapidly as other duties allow.
Many subjects will have no sub-section cards at the beginning; some will have no reference cards at the end; and some may have no titles given under the number. The scheme provides a place for books on all subjects, whether the library has them or not, so where no titles are given under a class number it shows that the library has as yet no books on that subject.
Articles in periodicals and transactions, separate volumes of sets and collections which are located together, if catalogued are put under their proper subject number, but no book number is given with it. The call number of the book, where they may be found, is always given in the margin preceded by the word IN. In the same way special chapters in books will sometimes be catalogued, e.g. a card marked 338 IN 331-27, would mean that in the 27 books on 331, Capital and Labor, there was a chapter on 338, Production.
