Should the Table of Contents be title case?

Question

I did read Which words in a title should be capitalized?

Now I'm asking myself when creating the "Table of Contents" for a book should I apply there the same rules for capitalization in the content list as for the title on the page. Or should I go with a lower case version like it is a normal sentence there.

Answer 1

Follow your style guide here. I would say: If you use a certain capitalization in the title of a chapter, then use the same capitalization whenever you mention that title elsewhere, including within the Table of Contents.
