William Gibson has a short story collection titled Burning Chrome. One of the stories in this collection is also titled Burning Chrome. I was recommending the book to someone and I wanted to say that of the short stories, the titular/eponymous story Burning Chrome was my favorite.
I believe both words are okay in this context but feel one would be more appropriate. Which one?
For titular, I'm using the 2nd definition found here: http://dictionary.reference.com/browse/titular?s=t
The book Burning Chrome is named after the titular story within.
For eponymous, I'm using the only definition here: http://dictionary.reference.com/browse/eponymous?s=t
The short story, Burning Chrome, gives its name to the larger collection of short stories, Burning Chrome.
