Are there definitive rules on how to punctuate a book title?
Yes, there are broadly accepted rules for book and chapter titles. They are very similar for properly punctuating titles for poems, short stories, songs and musical albums.
You can check a variety of references such as the Chicago Manual of Style, the AP Style Guide, The Oxford Style Guide and many others.
Your choice might depend on whether you are using American, British, Australian or Canadian English language style.
However, the generally accepted basic rules for punctuating book titles are quite standard across all forms of English.
