The logic of the for-loop is flawed; the expression 

title_split[0] in small_words

will always evaluate to True if the first word is a "small word", even when 
the loop is already past the first word. You can work around that with a 
flag along these lines

first = True
for word in title_split:
    if first:
        # special treatment for the first word
        first = False
    else:
        # put checks for all words but the first here
    new_title.append(fixed_word) # assuming you have stored the titlecased
                                 # or lowercased word in the fixed_word
                                 # variable
