The word following Same should generally begin with a capital.

160. Retain under the author only what is necessary to distinguish the work from other works of the same writer, but under the subject what is needed to state the subject and show how it is treated.

The preface of an excellent catalogue remarks that “the primary object of subject-entries is to inform the reader who have written upon a given topic rather than what has been written.” This is a mistake. The inquirer wishes to know both; in fact he wants to know who have written about it because their character will suggest to him what they have written. {71}

161. Retain both of alternative titles.

Ex. Knights and sea-kings; or, The Middle Ages.

The reason is that the book may be referred to by either title.

162. Retain in the author entry the first words of the title; let the abridgement be made farther on.

Because (1) it facilitates library work, by rendering the identification of the book quicker and surer; (2) if there is no part of the title which must be given, two persons may abridge so differently that not a single word shall be the same in the two abridged titles, so that two works will be made out of one (I have often known this to happen); (3) books are frequently referred to by the first word of the title (Grassi’s “Notizie sullo stato presente degli Stati Uniti” may be quoted as Grassi: Notizie). Short, however, can probably not afford to retain first words in all cases. Half the phrases used at the beginning of titles add little or nothing to the meaning, such as “Treatise on,” “System of,” “Series of lectures on,” “Practical hints on the quantitative pronunciation of Latin” (here “Practical hints” belongs in the preface, not in the title, to which it really adds nothing whatever). “History of” must often be retained under the subject. One can say

but under Athens that would not be enough; it would be necessary to write
