What Title Case actually does

Capitalising every word is not title case. Style guides keep short joining words — a, an, the, and, or, of, in, on — in lower case unless they open or close the line.

So "The Lord of the Rings" is title case; "The Lord Of The Rings" is a tool that did not know the rule.
