Hello! Can't seem to find the answer to this question anywhere so I figured I would ask it myself.

Are subtitles supposed to be capitalized even if on the cover of the book they are not? Is it "A Good Book: This is the subtitle" or "A Good Book: This Is the Subtitle"? Obviously this is easily answered when the subtitle is capitalized on the cover, but I wasn't sure what the policy was otherwise.

Hi, yes all data in the title field should be capitalized per policy, no matter how it is displayed on the cover image. For English language editions it would be "A Good Book: This Is the Subtitle" as you say.

For editions in other languages than English, the standard capitalization rules can be different. For example for a Swedish edition, the correct capitalization would be "A good book: This is the subtitle"
