Doctor Who General:Style Guide

"''Spelling titles incorrectly on purpose is illogical and should be avoided. I have explained numerous times that, almost always, the "of" and "the" are not to be capitalised. Therefore, you should not write them with capital letters. Such conjunctions and prepositions do not require capitalising, to do so is incorrect. Do not do it.

That is all.''" - Our friend in Telford
