I'm about to submit an article to a journal for review. There is a published book (about 5 years old) that has the same title as my working paper. As you might guess, the paper and book are in the same subfield of study. The shared title is cute variation on the name of a prominent organization (which honestly fits my paper better than the book).
Do I need to change the title of my paper? Another thing to consider is that the author of the book is a likely candidate to be selected as a reviewer for the article.
