The 16th edition of The Chicago Manual of Style made a couple of changes for how to cite website addresses.
When used as a title/heading, should the second part of a hyphenated word be capitalized or not (examples: Chapter Twenty-One, Fifty-first Street)?
The 15th edition of The Chicago Manual of Style said that “Southern California” should have both words capitalized, but “northern California” should not. This has changed in the 16th edition.
An ellipsis indicates the omission of a word, phrase, line, paragraph, or more from a quoted passage. Ellipsis points are also used to indicate suspended or interrupted thought. But how should an ellipsis be typed? This has changed with the new edition of The Chicago Manual of Style.
Capitalize terms of endearment (honey, dear, sweetheart) or not? The Chicago Manual of Style‘s 15th edition said they should be lowercased. Now?
All caps or small caps or lowercase, with periods or without, for AD/BC and AM/PM?
The Chicago Manual of Style has changed some of the rules for forming the possessive of proper names.
Another change from the 15th edition of The Chicago Manual of Style to the new 16th edition refers to commas used with question marks or exclamation marks.
