Giving my article the same title as a published book by another author

I'll be perfectly honest - if I was in that subfield, I would be extremely annoyed in having two works with the same title - simple search for the works would be always troublesome, mentioning one of those works during a talk would always require a digression, etc.

All of that would distract other researchers from the results, especially for the paper considering that it was published later. Ultimately it is not inconceivable that referee (whoever it might be) demands the change of the title.

Bottom line - I would try to think another witty title. :)

There's no legal issue with two creative works having the same title, but I would want to have a different title so that people could easily distinguish the two works. I would want it to be very clear that there's a new article that's available that's distinct from this book. As such, I think you ought to change your title even if it's a better fit for your article than it is for the book. Cute titles can really only do so much.

My suggestion is a slight modification to the title. Another option is a sub-title or sub heading which is a unique identifier. For example, a book titled Arizona: Portrait of a desert landscape and another, slightly unique, titled Arizona: Understanding the Desert Landscape. Also, you can pluralize a word (face could become faces, for example) in the title of your book, for distinctiveness.

Consider the book titles Bill Gates: Entrepreneur and Bill Gates: Master Innovator. Both titles have the same name, as they are about the same person, but the sub heading or sub title is unique.
