ITALIC TYPE
NOTE.—A list of foreign and anglicized words and phrases, showing which should be printed in roman and which in italic, is given on [pp. 35-7].
In many works it is now common to print titles of books in italic, instead of in inverted commas. This must be determined by the directions given with the copy, but the practice must be uniform throughout the work.
Words or phrases cited from foreign languages (unless anglicized) should be in italic.
