The subject, title, and subtitles of your book or article are the guts of your work and its basic skeleton, respectively. Without them you cannot create structure, content, or a sense of your material. In order for your work to make sense, you must limit or draw boundaries around a portion or niche of your subject matter. If you have no boundaries or niche, then your writing becomes ineffective and does not accomplish your intent or persuasively convey your thesis or initial assertions.
For example, if I want to write an article on higher education, then I must decide how I will approach the subject, what facet of the process of higher education I will address, and to what extent I will explore or expose that facet. If I decide I want to explore the value of non-classroom experiences for instance, then I will need to assert certain ideas in the creation of my thesis or initial assertions. I will then create my structure, including my title and subtitles, based on the initial assertions defined in the thesis.
Here is how my subject, title, and subtitles may help define my structure in my example:
Subject: The Value of Non-classroom Experiences in the Process of Higher Education
Thesis: Professional educators estimate that approximately 95% of the value of higher education lies in the student's experiences outside of the classroom in the process of obtaining of a four year degree. We will explore these experiences and how they may be assessed as having a significant value in the student's education process.

Tear Down the Wall? Why it all Matters.
Using this thesis, subject, title, and subtitles I can construct an entire structure and outline for my new book. Yes, I have heavily borrowed references from Pink Floyd's old The Wall album in which Another Brick in the Wall was the title of the main trilogy. But, properly notated and credited I can succeed with it. Since the 1979 album, now CD, The Wall, confronts authority, education, and the system, it is a reference that will heavily convey the underlying message of the thesis: the real value is in the individual rather than the system.
As a nonfiction writer, the juxtaposition of The Wall's ignorant mantra, "We don't need no education," with the thesis serves as a creative way to catch and keep the reader's attention. Between the first two subtitles and the last subtitle are other subtitles that will later serve as chapters to more clearly define for the reader the why, where, and how of the value of external experiences in the process of higher education.
Incorporating Pink Floyd's ending, "Tear Down the Wall" into the last subtitle helps to wrap up the writer's assertions from the thesis. While its incorporation at the end also paints Pink Floyd's conclusion as an absurd notion since the writer concludes and emphasizes the value of the most mundane outside the halls of higher education, the implication of it helps to strengthen the writer's assertions.
While such creative practices take time to develop, they are not outside of the acceptable realm of nonfiction writing. If you think it is, then ask yourself why you see so much social context referencing in the titles and subtitles of magazine and newspaper articles. Simply put, it helps the nonfiction writer get the attention of the reader and it helps to make a connection with the reader. Using another work of art, music, or fiction as a juxtaposition reference in the context of nonfiction writing does not diminish the facts or seriousness of your nonfiction content. You should, however, not expect to jump straight into this style of writing as it takes time to develop a style conducive to creative borrowings.
Even a novice, however, can implement such strategic handling of social or artistic content if they use it as a basis for the titles, subtitles, and structure of their content. The key to doing so effectively is to avoid overdoing it. Too much explanation or too much implication ruins the impact of creative borrowing and diminishes your work's originality. To be an effective nonfiction writer, you must be original, even if you borrow a phrase or two or incite certain notions by referencing musical works.
