When a writer has contributed more than one volume to the work the entries can be amalgamated in this fashion

Sanday, Wm. International critical commentary:
Synopsis of the four Gospels. The Epistle to
the Romans. 2 v. 1907-13220.7

In the event of it being decided to give references instead of entries under the names of the authors of the separate volumes, such references must direct to the entry where the contents of the volumes are set out, otherwise the connection will not be apparent. The contents being under "Bible" in the above instance, the reference should read

Skinner, John. See Bible (Commentaries):
Driver. International critical commentary.

Without the latter part this reference would be too indefinite to be useful. The entry itself, first shown under Skinner, takes hardly less space, and is preferable.

When a book is what may be called a monograph-commentary, i.e., a book standing alone upon a single book or two or three books of the Bible, it receives the same treatment as would any other work, irrespective of its connection with the Bible. For example

Tholuck, A. Commentary on the Gospel of St.
John. 1860226.5

is placed with any other books upon the Fourth Gospel, as

John, St., Gospel of:
Tholuck, A. Commentary on the Gospel of
St. John. 1860226.5
