SUBJECTS.

(a.) ENTRIES CONSIDERED SEPARATELY.

92. Some questions in regard to the place of entry are common to the

author- and the subject-catalogue; because individuals (persons,

places, ships, etc.) may be at once authors and subjects. For these

questions consult Part I, and also § 100 of the present part.

In a dictionary catalogue some books can not profitably have

subject-entry, because they not only have no one subject but do not

even belong to any class of subjects.

A collection is to be entered under the word which expresses

its subject or its general tendency. The memoirs, transactions,

proceedings, etc., of a society should be entered under name of

the object for which the society is founded. When there are many

societies under one head, it is economical to refer merely; as, from

«Agriculture» or «Agricultural societies» to the various names.

The importance of deciding aright where any given subject shall be

entered is in inverse proportion to the difficulty of decision. If

there is no obvious principle to guide the cataloguer, it is plain

there will be no reason why the public should expect to find the

entry under one heading rather than another, and therefore in regard

to the public it matters not which is chosen. But it is better that

such decisions should be made to conform when possible to some general

system, as there is then more likelihood that they will be decided

alike by different cataloguers, and that a usage will grow up which

the public will finally learn and profit by, as a usage has grown up

in regard to the author-entry of French names containing De, Du, La,

etc.

(i.) CHOICE BETWEEN DIFFERENT SUBJECTS.

(_a._) _Between general and specific._

93. Enter a work under its subject-heading, not under the heading of a

class which includes that subject.

_Ex._ Put Lady Cust’s book on “The cat” under «Cat», not under

«Zoölogy» or «Mammals», or «Domestic animals»; and put Garnier’s “Le

fer” under «Iron», not under «Metals» or «Metallurgy».

This rule of “specific entry” is the main distinction between the

dictionary-catalogue and the alphabetico-classed.

Some subjects have no name; they are spoken of only by a phrase or

by several phrases not definite enough to be used as a heading. A

book may be written on the movements of fluids in plants, a very

definite object of investigation, but as yet nameless; it must be

put under Botany (Physiological). But if several works were written

on it and it was called, let us say, «Phythydraulics», it would be

seen that, under this rule, it no more ought to be under «Botany»

than «Circulation of the blood» under «Zoölogy». Thirty years ago

“Fertilization of flowers” could hardly have been used as a heading;

but late writings have raised it to the status of a subject. There are

thousands of possible matters of investigation, some of which are from

time to time discussed, but before the catalogue can profitably follow

its “specific” rule in regard to them they must attain a certain

individuality as objects of inquiry, and be given some sort of _name_,

otherwise we must assign them class-entry.

And it is not always easy to decide what is a distinct subject.

Many catalogues have a heading «Preaching». Is Extempore preaching

a sufficiently distinct matter to have a heading of its own? There

are a number of books on this branch of the {47} subject. In this

particular case the difficulty can be avoided by making the heading

“«Preaching without notes.»” Many such questions may be similarly

solved, with perhaps more satisfaction to the maker of the catalogue

than to its users; but many questions will remain.

Then, mixed with this, and sometimes hardly distinguishable from

it, is the case of subjects whose names begin within an unimportant

adjective or noun,—Are of the meridian, Capture of property at sea,

Segment of a circle, Quadrature of the circle. All that can be said in

such cases is that, if the subject be commonly recognized and the name

accepted or likely to be accepted by usage, the entry must be made

under it. For the fuller discussion of compound headings, see §§ 106,

107.

On the other hand, difficulty arises from the public, or a part of

it, being accustomed to think of certain subjects in connection with

their including classes, which especially happens to those persons

who have used classed catalogues or the dictionary catalogues in

which specification is only partially carried out; so that there is

a temptation to enter certain books doubly, once under the specific

heading to satisfy the rule, and once under the class to satisfy the

public. The dictionary principle does not forbid this. If room can

be spared, the cataloguer may put what he pleases under an extensive

subject (a class), provided he puts the less comprehensive works also

under their respective specific headings. The objection to this is

that, if all the specifics are thus entered, the bulk of the catalogue

is enormously increased; and that, if a selection is made, it must

depend entirely upon the “judgment,” _i. e._, the prepossessions and

accidental associations, of the cataloguer, and there will be an

end to all uniformity, and probably the public will not be better

satisfied, not understanding why they do not find class-entry in all

cases.

(_b._) _Choice between person and country._

94. Put under the name of a king or other ruler all his biographies,

and works purporting to be histories of his reign; but enter under the

country all histories which include more than his reign and accounts of

events which happened during the reign, and all political pamphlets not

directly criticising his conduct.

The first part of this rule is analogous to that by which the works of

a king of a private nature are put under his name, and all his public

writings under the country; putting histories of the reign under the

king is partly subject- and partly title-entry. Books of this sort

have really two subjects and ought to be entered twice (_e. g._,

Boutaric’s “La France sous Philippe le bel”); the rule above is simply

an economical device to save room at the expense of convenience.

Perhaps a better practice would be to enter all lives of kings as well

as histories of their reigns under the country only, with a reference

from the king.

Similarly there are some biographies and autobiographies which have

such a very large proportion of history that they ought to appear

both under the man and the country. In general we merely refer from

the country, but occasionally nothing but double entry will suffice.

Whether they shall appear by way of entry or merely be mentioned in a

note, must be determined by circumstances.

(_c._) _Choice between event and country._

95. Events[37] or periods[38] in the history of a country which have a

proper name may be entered under that name with a reference from the

country; those whose name is common to many countries[39] should be

entered under the country.

[note] 37. St. Bartholomew’s day.[/note]

[note] 38. Fronde.[/note]

[note] 39. Revolution; Restoration; Civil war.[/note]

{48}

(_d._) _Choice between subject (or form) and country._

96. The only satisfactory method is double entry under the local and

the scientific subject—to put, for instance, a work on the geology of

California under both «California» and «Geology», and to carry out

this practice through the catalogue, so that the geographical student

shall not be obliged to search for works on California under «Botany»,

«Geology», «Natural history», «Palæontology», «Zoölogy», and a dozen

similar headings, and the scientist shall not be sent to «California»,

«England», «Russia», and a score of other places to find the various

treatises on geology. But as this profusion of entry would make the

catalogue very long, we are generally obliged to choose between country

and scientific subject.

97. A work treating of a general subject with special reference to a

place is to be entered under the place, with merely a reference from

the subject.

_Ex._ Put Flagg’s “Birds and seasons of New England” under «New

England», and under «Ornithology» say _See also_ «New England». As

«New England ornithology» and «Ornithology of New England» are merely

different names of the same specific subject, it may be asked why we

prefer the first. Because entry under «Ornithology of New England»,

though by itself specific entry, is when taken in connection with the

entries that would be grouped around it («Ornithology», «Ornithology

of America», «Ornithology of Scotland», etc.), in effect class-entry;

whereas the similar grouping under New England does not make that a

class, inasmuch as «New England botany», «New England history», «New

England ornithology» are not parts of New England, but simply the

individual New England considered in various aspects. Of course the

dictionary catalogue in choosing between a class and an individual

prefers the latter. Its object is to show at one view all the sides

of each object; the classed catalogue shows together the same side of

many objects.

There is not as yet much uniformity in catalogues, nor does any carry

out this principle so absolutely as the more obvious “specific” rule

is obeyed. The Boston Public Library Supplement of 1866, for instance,

has under the country _Antiquities_, _Coinage_, _Description_ and

_History_, _Language_, _Religion_ (subjects), and _Literature_,

and even _Elocution_ and _Poetry_ (forms), but not _Ballads_ nor

_Periodicals_, which appear under those words. Yet when Ballads are

called Volkslieder they appear under the country Germany,—an instance

of the independence of the title produced by foreign languages, the

English title being entered by form-word, the foreign works having

national classification, regardless of the title. There are many other

classes that in most catalogues at present, instead of being confined

to general works, absorb books which should rather have local entry,

as «Vases», «Gems», «Sculpture», «Painting», and other branches of

the fine arts, «Ballads», «Epigrams», «Plays», and other forms of

literature. In catalogues of merely English libraries this is perhaps

as well (see § 122), but the multiplication of books and the accession

of foreign literatures render more system necessary.

To show the procedure under this rule, suppose we have a collection

of books on coins. Let the general works go under «Numismatics»; let

works on any particular coin, as a «Pine-tree shilling» or a «Queen

Anne’s farthing», go under the name of the coin; let works on the

coins of a country be put under its name; refer from the country

to all the particular coins on which you have monographs, and from

«Numismatics» both to all the separate coins and to all the countries

on whose coinage you have treatises. {49}

(_e._) _Between subjects that overlap._

98. Among subjects that overlap choose the one that preponderates, with

a reference from the other.

_Ex._ Any complete treatise on domestic animals will cover a large

part of the ground of veterinary medicine; but it is unnecessary to

enter all the works on domestic animals under «Veterinary medicine»;

a note to this effect is sufficient. «Astronomy» and «Geology»

overlap in regard to the origin of the earth, «Geology» and «Physical

geography» in regard to its present condition. Any particular book

must be classified with one or the other subject according as the

geological or geographical treatment prevails.

(ii.) CHOICE BETWEEN DIFFERENT NAMES.

99. General rules, always applicable, for the choice of names of

subjects can no more be given than rules without exception in grammar.

Usage in both cases is the supreme arbiter,—the usage, in the present

case, not of the cataloguer but of the public in speaking of subjects.

(_f._) _Language._

100. When possible let the heading be in English, but a foreign word

may be used when no English word expresses the subject of a book.

_Ex._ «Écorcheurs», «Émigrés», «Raskolnik». Many terms of the Roman

or civil law are not exactly translatable; neither Fault nor Crime

gives the idea of Culpa; the Debitor inops is not our bankrupt or

insolvent; he would have been very glad to have the privileges of

a bankrupt. Some other technical terms, and some names of bodies,

sects, events, should be left in the original language. The use of

the Latin names of Greek deities (Jupiter, Neptune, Venus, in place

of Zeus, Poseidon, Aphrodite) is a manifest inaccuracy. Yet it may be

defended on the plea: (1) that the Latin names are at present more

familiar to the majority of readers; (2) that it would be difficult to

divide the literature, or if it were done, many books must be put both

under «Zeus» and «Jupiter», «Poseidon» and «Neptune», etc., filling

considerable room with no practical advantage.

On the language of place names, see § 33, 35.

(_g._) _Synonyms._

101. Of two exactly synonymous names choose one and make a reference

from the other.

_Ex._ «Poisons» and «Toxicology»; «Antiquities» and «Archæology»;

«Insects» and «Entomology»; «Warming» and «Heating»; «Pacific Ocean»

and «South Sea». There are some cases in which separate headings

(«Hydraulics» and «Mechanics of Fluids»), which can not be combined,

cover books almost identical in character, so that the inquirer

must look under both. This is an evil; but there is no reason for

increasing the evil by separating headings that are really synonymous,

certainly not for dividing a subject in this way for verbal causes and

giving no hint that it has been divided.

It sometimes happens that a different name is given to the same

subject at different periods of its history. When the method of study

of the subject, or its objects, or the ideas connected with it, are

very different at those two periods (as in the case of «Alchemy» and

«Chemistry»), of course there must be two headings. There is not so

much reason for separating Fluxions and Differential calculus, which

differ only in notation. And there is no reason at all for separating

«Natural Philosophy» and {50} «Physics». I am told that medical

nomenclature has changed largely three times within the present

century. How is the cataloguer, unless he happens to be a medical

man, to escape occasionally putting works on one disease under three

different heads?

To arrive at a decision in any case one must balance the advantages on

the one hand of having all that relates to a subject together, and on

the other of making that economical conjunction of title-entry and of

subject-entry which comes from following the titles of the books in

selecting names for their subjects.
