I reckoned the approach with the flag the most beginner-friendly because you 
don't have to think too hard about the corner-cases, namely

>>> book_title("")
''

When I use the "process first item before the loop" approach I usually end 
up with a helper generator

def _words(words, small_words={w.title(): w for w in small_words}):
    yield next(words)
    for word in words:
        yield small_words[word] if word in small_words else word

def book_title(s):
    return " ".join(_words(iter(s.title().split())))

and the nagging thought that I'm making it more complex than need be.

	title_split[0] will never change, so if it is one of the small
words, then all subsequent words will also be treated to this branch.

>             new_title.append(word.lower())

	You already lowercased all the words before splitting, so this is
applying lowercase to a known lowercase word

	I'd suggest looking up the definition of

enumerate()

in the language documentation... It will give you a simple way to know
if you are looking at the first word. Basically, you want to title-case
the word IF it is the first word OR the word is NOT in the list of
lowercase words; anything else goes through as lower case...

	Of course, most of this can be done in a single line (including
taking into account that some words may have a punctuation mark which
would confuse the original).

>>> smalls = ['into', 'the', 'a', 'of', 'at', 'in', 'for', 'on' ]
>>> punct = ".,;:?!;'\"(){}[]"
>>> def recase(str = "physicist odd-affection, or how i was taught to stop fretting and adore the weapon of mass destruction"):
... 	return " ".join( w.title() if i == 0 or w.strip(punct) not in
smalls else w
... 			for i,w in enumerate(str.lower().strip().split()) )
... 
>>> recase()
'Physicist Odd-Affection, Or How I Was Taught To Stop Fretting And Adore
the Weapon of Mass Destruction'
>>> recase("what? me worry?")
'What? Me Worry?'
>>> recase("the end of the matter is, to be blunt, a confusion")
'The End of the Matter Is, To Be Blunt, a Confusion'
>>> recase("the end of the matter is in, to be blunt, a confusion")
'The End of the Matter Is in, To Be Blunt, a Confusion'
>>> smalls = ['into', 'the', 'a', 'of', 'at', 'in', 'for', 'on', "and", "is", "to" ]
>>> recase()
'Physicist Odd-Affection, Or How I Was Taught To Stop Fretting and Adore
the Weapon of Mass Destruction'
>>> recase("the end of the matter is in, to be blunt, a confusion")
'The End of the Matter is in, to Be Blunt, a Confusion'
>>> 

	Of course, explaining what this construct is doing is the trick to
justifying it for a homework assignment.

Too much destruction in this post man, and yeah I would not be able to
explain the code for my homework.
