72.—Sometimes the commentaries in a series are of sufficient importance, or of such a character, that each is virtually a book quite apart from its place as one of the series. The volumes of the Expositor’s Bible, edited by W. Robertson Nicoll, are of this class, and, while they should in the first place be dealt with as shown in the Cambridge Bible above, yet a mere reference under the author’s names hardly suffices—they are not merely editors as in the Cambridge Bible series—therefore, besides this principal-entry under Bible, entries are required, as

Farrar, F. W., Dean. The first Book of Kings. (Expositor’s Bible). 1893

⸻ The second Book of Kings. (Expositor’s Bible). 1894

⸻ The Book of Daniel. (Expositor’s Bible). 1895

or in a style more concise

Farrar, F. W., Dean. Expositor’s Bible:

I. and II. Kings. 2 v. 1893-4

Daniel. 1895

Though coming more correctly under the remarks on subject-headings it may be here noted in passing that commentaries in a series are regarded as a single book and not entered separately under the name of each book of the Bible throughout the catalogue, therefore the above items would not have entries under “Kings” or “Daniel.” If, however, Dean Farrar had written a separate work dealing with the Book of Daniel, it should be entered under “Daniel,” and not under “Bible.” So commentaries, or any other works upon the whole Bible, like the entire series of the Expositor’s Bible, go under “Bible,” but if the commentaries deal with the Old or New Testament, or any particular book of the Bible separately, such works are placed under the headings of “Old Testament,” “New Testament,” or under the name of the particular book dealt with, as the case may be, and not under the heading “Bible,” as in the case of the text alone, or any portion of it. There are exceptions even to this rule with regard to translations, if special, and more particularly if accompanied by an exposition, as in a case like
