Headlines and Titles of Works

Q. CMOS 14.195 explains how to include the headline names of regular columns or features in a footnote citation, but how should they appear if mentioned in the main text: italicized, in quotes, or roman? Thanks!

Q. Should “that” be capitalized in titles? Does it depend on usage? Take, for example, this title: “Features of the Website That Are Offered as Premium.” Thanks!

Q. An author of a book I’m copyediting wishes to italicize the books of the Bible (Genesis, etc.) on the grounds that the convention of using roman type for sacred works is based on the assumption that these texts were divinely inspired rather than authored by humans (an assumption this author is challenging). The author would add a note explaining this style choice.

I cannot, however, find anything about the basis for the rule that the titles of “highly revered works” (from CMOS 8.103) should not be italicized. Do you know the original rationale for the convention?

Q. Is it okay to write “New York Times bestseller” even though the list is called “The New York Times Best Sellers”? The advice in CMOS 8.172 does not really cover this scenario. Thank you!

Q. What is the correct way to write “four o’clock” as a book title?

Q. In CMOS 8.161 (on hyphenated compounds in headline-style titles), the word “Speaking” in the example “Non-English-Speaking Representatives” is capitalized, going against rule 3. Since “non-” is a prefix and cannot stand alone as a word, shouldn’t “speaking” be lowercase? Thank you for your explanation.

Q. When an author publishes a work that violates Chicago’s headline capitalization style, should we convert the citation to Chicago style or leave it as the author designated? Is this discussed anywhere in CMOS?

Q. Is the word “to” capitalized in a title or heading when used as part of an infinitive verb?

Q. I work on science textbooks and science trade books (I wonder why I’ve never needed to ask this question before) and have this question: Does one capitalize “sp.” (or “spp.”) in titles? For example: “Dinarda Spp.: The Sneaky Thief.” Unabbreviated, the word “species” would be capitalized. However, were it the actual species name, it would be lowercased. It does look odd capitalized, since it is never so in text, but I’m leaning toward capitalization as being correct. Possibly the answer to this question lies within (within CMOS, that is), but if so I’ve not been able to find it. What say you?

Q. Hello: When using headline-style capitalization (CMOS 8.159), does a participial preposition (CMOS 5.175) appear in lowercase or uppercase? Thanks very much.
