Okay, I explained that a little badly… I am
well aware of what title case is, and how it functions, as well as variations, etc. What I don't get, it why the chapters are
1. not following any one pattern. The first few are in sentence case, for starters (only the first word, "I," and proper nouns). And please, don't refer to capatizing the first letter of every word as "proper," it's called "start case" and it really is incorrect and careless (at least whomever
teaches it as correct is).
2. in some cases the capitalization in other cases is all but random. In chapter 5, "is not" is lower case, when it shouldn't be (length only affects the capitalization of prepositions and conjunctions, after all), and chapter 8 follows suit. There's also chapter 12: "I want to Take Care of My older Boyfriend" — that one really had me puzzled. (Is "I Want to Take Care of My Older Boyfriend" that hard?)
Also to correct your information of title case: It isn't the
importance of the word which determines whether it is capitalized in title case (that's actually irrelevant), it is the
part of speech and
length: only articles, conjunctions, and prepositions are
ever lower case, and those only when they are less than four or five letters long (depending on who you ask). This originates in a confusion regarding German captialization rules, which were sometimes used to make titles stand out, but due to the already-present differences regarding the treatment of the derivatives of proper nouns (among other things), things got mixed up and the present system developed ultimately developed (so, yeah, newspapers didn't have a hand in this one). The only other time a word may be left uncapitalized in English title case is when it is a phrase from another language, in which case the phrase is italicised and follows its native capitalization rules (e.g. any titles including a Latin term, or one from a Romance language, would not be capitalized apart from proper nouns). Aside from whether four letter prepositions and conjunctions are capitalized, there is also no consensus on the capitalization of hyphenated words, however, aside from those two things, the rules proper English capitaliztion are all but set in stone (there are always those few who try to use other systems and confuse and annoy the Hell out of everyone else, but that's life for you). Basically the only actual difficulty is recognizing the part of speech for words which can be used in multiple (e.g. "on," "up," "but," and "so").
In short, what I meant was that the use of title case is very irregular for this series and doesn't follow any kind of pattern. Sorry if I confused you.
To whomever fixed this chapter's title: Thank you!
